This pot of green plants put nutrient solution and water glue, why will the leaves turn yellow?

Hello, you can look for the root of the problem from the following.

Causes of yellowing of leaves of hydroponic plants:

1. Insufficient water and nutrients. Hydroponic plants have high requirements for water quality, and the water in the hydroponic container must not only be abundant to soak the flower roots, but also have sufficient nutrients. The nutrients in the water are still there after being absorbed by the roots of the plant, so it is not that there is water that has an effect, and replacing the water in time can ensure that the leaves of hydroponic plants will not turn yellow.

Hydroponic greenery. 2. Unreasonable sun exposure: hydroponic plants just don't need to bask in the sun every day, but the leaves of hydroponic plants will also turn yellow if they don't accept sun exposure for a long time. The most reasonable breeding method is to dry once or twice a week, and keep it for two or three hours each time.

3. Nutritional supplementation is not timely. Hydroponic plants only have water, and a nutrient solution must be added to the water.

in order to make them grow healthily. Do not put too much nutrient solution, five hundred milliliters of water to add three drops of nutrient solution is enough, in addition, it is recommended to use some Vosch Wo leaf potassium dihydrogen phosphate.

It can increase the color of the leaves and meet the nutrient needs of plants.

There should be two reasons. First, the watering is big, and you are watering it every day, and you almost watered the flower to death. Raising flowers should follow the principle of dry and watering, which means that the surface of the flower soil in the pot is about 3 cm dry before watering; Second, it is better to replace the flower soil regularly, once a year, or fertilize the flowers regularly.

However, when buying flower soil or flower fertilizer, be sure to tell the stall owner what kind of flowers you raise, and the stall owner will prepare suitable flower soil or flower fertilizer for you.

Raising flowers is long-term, in the case that the flower roots can not absorb nutrients, or in the case of long-term watering and soaking the roots badly, you can no longer water the nutrient solution or other nutrient water.

Fugui bamboo is very easy to raise, but the leaves are easy to turn yellow before it takes root and survives.

Now the indoor temperature is low, the plant grows slowly, it can take about 45 days to take root, after rooting, the leaves will no longer turn yellow, slowly raise it.

Fugui bamboo is more shade-tolerant, put it in a bright place indoors, change the water once a week, it is better to spray potassium dihydrogen phosphate on the leaves, prune the yellow leaves, the problem is not big, rest assured.

Take a closer look at the back of the leaf to see if there is a red spider, there is an insect infestation, and the leaves are also easy to yellow, if there is a red spider, go to the flower shop to buy a package of plant insecticides to remove mites, a pack of a watering can, spray the plant leaves and branches, and spray three or four times a week.

If it is diluted according to the instructions, it should not be too high, and you can see if it is caused by other causes of yellowing of the leaves. In general, there are several reasons why the leaves of hydroponic plants turn yellow:

1. Insufficient light. The normal growth of flowers requires a certain intensity of light, and if it is placed in a shaded environment, it will cause a large amount of leaf loss.

2. No ventilation. If the indoor air is not circulated, the oxygen content of the water in the hydroponic plant will drop sharply, causing the plant to turn yellow and lose its leaves due to lack of oxygen.

3. The temperature is too low. When the ambient temperature is lower than the safe overwintering temperature, due to the weakening of the physiological activity of the plant and the reduction of absorption capacity, the plant will shed a part of the leaves to adapt to the low temperature environment in order to reduce the consumption of water. In severe cases, the blades will completely fall off, leaving only the bare rods.

4. The concentration of nutrient solution is too high. Concentrations that are too high can cause fertilizer poisoning, which can cause defoliation.

Insufficient concentration of nutrient solution: 1. The yellowing of the old leaves is a lack of nitrogen, and the loss of green veins is a lack of magnesium.

2. The yellowing of new leaves is caused by a lack of medium and trace elements (iron, manganese, calcium, etc.).

5. Failure to change the water in time. When the water change interval is too long, the oxygen in the water cannot meet the needs of flower growth, and the number of microorganisms increases, which often causes root rot of hydroponic flowers. Since the absorption of water and nutrients is greatly reduced after the flower rots, it will cause a large number of defoliation.

After figuring out what kind of situation it is, you can remedy it in a targeted manner**: if you lack fertilizer, supplement the special nutrient cord for hydroponic flowers; If there is a lack of light, place the potted flowers in a well-lit place indoors, and they can be restored after a week. If the yellowing of the old leaves in the lower part of the plant is a normal metabolism, such yellow leaves should be cut off to improve the ornamental nature of the plant.

If the concentration is too high, stop using it for a while.

Originally, hydroponic nutrient solution watering soil culture plants will not cause seedling burning due to excessive concentration, but if there is an abnormality, change the potting soil and water.

It is caused by the concentration of the nutrient solution is too large, and spraying more water every day can alleviate it.

Fertilization should not be applied during the dormant period, less fertilizer and more water during the growth period, and it is easy to burn leaves when it is hypertrophied. Yellow less plucked, more yellow, after Qingming left more than ten centimeters, the above part of the cutting, the cut branches can be cuttings, the pot will regenerate new branches.

Routine care is very convenient, just pay attention to the following points:

1. Suitable ambient temperature: The growth temperature of hydroponic plants is 5 -30, and they can grow normally in this range.

2. Appropriate light: The light of hydroponic plants is mainly scattered light, and it does not necessarily have to be exposed to the sun. In summer, direct sunlight should be avoided as much as possible.

3. Change the water and clean the roots of the flowers: The hydroponic plants should be changed about once every 7 days in summer and 10-15 days in winter, and a few drops of special nutrient solution for hydroponic flowers should be added (the concentration of the nutrient solution should be prepared according to the requirements of the manual). Vessels used to grow hydroponic plants are prone to moss, which affects the ornamentation of the root system and consumes oxygen in the water.

When changing the water, you should first wash off the mucus of the flower roots with clean water, and cut off the old roots and rotten roots. And wash the utensils and roots with moss. Each time the water is changed, the interface of the water should be 1 2-2 3 of the submerged root system, and the rest of the root segments should be exposed to the air.

4. Moisturizing and spraying foliar fertilizer: In order to prevent the occurrence of leaf drying, during daily care, foliar moisturizing should be sprayed with water, and it is best to spray foliar fertilizer once a week, which can not only provide nutrients for the leaves, increase the luster of the foliar surface, but also achieve the purpose of resisting low temperature in winter. Judgment of nutrient deficiencies in hydroponic plants Nitrogen deficiency:

The growth is slow, the leaf color is yellow, and in severe cases, the leaves fall off. Phosphorus deficiency, abnormally dark green color, or gray spots, purple spots, delayed maturation. Potassium deficiency:

Dicotyledonous leaves, first lacking green, then scattered dark necrotic spots; In monocots, the apical and marginal cells of the leaf first die and then expand downward. Calcium deficiency: the development of buds is inhibited, the root tips are necrotic, the plants are dwarfed, and there are dark wrinkled leaves.

Magnesium deficiency: green deficiency occurs between the veins of old leaves, late flowering, light spots, white later, and finally brown. Iron deficiency:

There is a clear green deficiency between the leaf veins, and in severe cases, it is burning, similar to magnesium deficiency, except that it usually occurs on more tender leaves. Chlorine deficiency: The leaves first wilt, then turn green and necrotic, and finally turn bronze.

Boron deficiency: Plants are physiologically disordered, showing a variety of symptoms, most of which are the death of meristems at the tips of stems and roots. Plants should be carefully inspected when they show the above symptoms.

Sometimes it is caused by a deficiency or deficiency of a nutrient in the nutrient solution, sometimes it is caused by the pH of the nutrient solution, or a lack of several nutrients at the same time. No matter what kind of symptoms the plant has, it should be changed in time and the special nutrient solution for hydroponic flowers should be added.

The color of the leaves is determined by the color of the plastid in it, and most of the leaves are green because there are chloroplasts that carry out photosynthesis, and if the plant is placed indoors, it will not be able to get enough light and cannot photosynthesize normally, so the chloroplasts will naturally transform into chromosomes and white bodies, so the leaves will slowly turn yellow. Don't worry though, just put the plant back in a place where there is light and it will turn green again.

This is mainly not to get the transitional light, but directly from the shade to the yang caused, the plant needs a transitional way to see the light, there is no link in it, any plant can not bear, the plant in the original more yin environment suddenly came to the all-yang environment, will be burned by the sun, and the leaves turn yellow, brown, white, the burned leaves can not be recovered, can only look forward to the new leaves to grow sooner, and there must be a transition link to the sun to the flowers in the future.

You're in a hurry! Rinse it with water a few times and leave it with a little water. I just bought the rich bamboo, the root system has not yet developed, it takes a period of time, do not add any nutrients, in fact, the water is enough, and when the time is long, it is also possible to add some nutrient solution when the root system is more (a small amount can be).

If there is no root system or few root systems, it is easy to cause seedling burning.

Directly change the water after a few days, cut off the yellow leaves, it will grow again, just bought you change the water will have such a reason, after a few days will be fine, and then add a little bit of nutrition to normal.

It doesn't absorb water well, so you have to cut off a small section and put it in clean water to raise it when you just buy it.

Don't add nutrient hydraulics, you just put a few iron nails in the water, it needs an iron-containing substance.

Wenzhu Fugui bamboo is easy to yellow leaves? Don't worry, feed some "willow water", the leaves are verdant green to dripping oil.

Lack of nutrients. Change the water and add some hydroponic nutrient solution. To add often. It should be fine.

Hydroponic plants cannot be short of water, and the edges of the leaves always turn yellow, which is the cause of the lack of fertilizer. The nutrient solution is poured once a week. At the same time, foliar fertilizer is sprayed to replenish nutrients.

Hydroponic plants should be properly added with fertilizer or nutrient solution in water. This type of large-leaved plant generally does not need sun exposure, otherwise it is easy to burn the leaves. In addition, pay attention to temperature and air humidity, most people prefer a high temperature and humidity environment.

1.There are certain reasons for the leaf yellowing of hydroponic plants, such as the water quality deteriorates due to the long-term failure of the bottle of water, and the appearance of odor leads to the yellowing of the leaves. It is best to change the water every 5-7 days, and each time the water is changed to two-thirds of the original bottle of water.

2.Insufficient nutrients are also easy to cause yellow leaves, and the nutrient solution is added dropwise after each water change, which can provide nutrients for the normal growth of hydroponic plants.

3.Long-term placement in the shade is also easy to cause yellowing of leaves. It can be moved to a sunny and ventilated place indoors to facilitate photosynthesis and reduce the phenomenon of yellow leaves.

Hydroponics is not a long-term solution, the key is that the nutrients in the water can not fully meet the needs of plant growth, and the roots should not be fully immersed in the liquid, otherwise it is easy to cause root rot due to lack of oxygen.

Hydroponics is a new type of indoor soilless cultivation of plants, also known as nutrient hydroponics: its core is to fix the plant rhizome in the planting basket and make the root system grow naturally into the plant nutrient solution, which can replace the natural soil to provide water, nutrients, temperature and other growth factors to the plant body, so that the plant can grow normally and complete its entire life cycle.

You can look at the stems and leaves to see if there is a situation like necrosis or decay or wilting, if there is a plant disease, but also to observe whether the leaves are evenly yellowed, if there is a virus disease, if the above situation does not occur, it may be a lack of nutrition, nitrogen deficiency, mainly the old leaves appear yellowing first, the new leaves are light green, magnesium deficiency is the loss of green between the leaf veins, there are clear reticular veins, there are a variety of color spots or patches, sulfur deficiency is the yellowing of new leaves, uniform green loss, thin plants, lack of manganese, green loss between leaf veins, Small brown spots, iron deficiency, loss of green between the veins of new leaves, and the development of pale yellow to whitish whole leaves

I made my hydroponic nutrient solution by myself, I went to the chemistry store and bought some medicines and some 250ml beakers, glass sticks, balances, droppers, 100 and 1000ml graduated cylinders, the recipe is:

a. Nutrient mother liquor.

4 Calcium nitrate hydrate 472 mg liters (the same below).

Potassium nitrate 202

Ammonium nitrate 80b nutrient mother liquor.

Potassium dibasic phosphate 100

Potassium sulfate 174

7. Magnesium sulfate 246 water

Trace element nutrient mother solution (1000 times the amount used, 1 liter of nutrient solution only uses 1 ml of trace element mother liquor).

7 grams of ferrous sulfate in water (the same below).

EDTA 2 sodium.

Boric acid, manganese sulfate 4 water.

7 Zinc sulfate water.

5. Copper sulfate in water.

Ammonium molybdate is about 400 500 yuan in total, I bought it seven years ago, do vegetable soilless cultivation, the amount is large, but it has not been used up for seven years, it is very cost-effective, but the configuration should pay attention to a, b and trace elements to be matched separately, with a and then with b, and finally with trace elements, trace elements to be boiled EDTA 2 sodium first, and then add ferrous sulfate into Ao, turn brown and yellow, and the calculation formula, you can match 100 times, 250 times, 500 times the actual amount of mother liquor as needed Dosage (milligrams or grams) * multiple 1000 (or the required capacity) It is recommended to use a capacity of 1000, you can also go to see if there is a ready-made one to buy in the flower market, but I think I have a better match, although it is troublesome, but rest assured that you can buy chemical pure, it will be cheaper, I use the analytical pure, very expensive
