What if the leaves of white palm turn yellow in hydroponic culture?

I. sudden change in the environment

Reason: the newly raised white palm, because the environment has suddenly changed, it has not yet adapted, the leaves are easy to turn yellow, for example, after a sharp change in warm and humid light, the leaves will turn yellow before they adapt.

Method: in the process of conserving hydroponic white palm, it is best to reduce the change of its growth environment, if there is a problem, wait for it to alleviate and adapt to it.

Second, inappropriate lighting

Reason: if the sun is exposed to it, the leaves will be burned. There will be small yellow spots on the leaves facing the sun, and at the same time, the edges of the leaves will die easily and turn yellow completely slowly. If the sun is not enough, it will turn yellow, especially in winter or early spring, you need to give it good light, do not block it.

Solution: if the sun is too strong, you need to move it to a windy and cool area. Measures should be taken when the light is too strong. If you keep it in a cool area all the time, don't suddenly let the sun expose it, or it will turn yellow or die. You can leave it on the balcony for an hour in winter, preferably around ten o'clock. At the same time, the temperature should be controlled well. if it is difficult to control under special circumstances, it can be put in the air-conditioned room to regulate the temperature difference.

III. Improper fertilization

Reason: if the fat is too much, there will be fat yellow, the tip of the old leaf will yellow and wither, if it is a new leaf, the leaf surface will not be smooth and unstretched. If the fertilizer is not enough, the roots do not carry enough nutrients, and the leaves will be weak and yellow.

Method: to moderate reduction of fertilizer, the amount should be less, the frequency should be more. If the yellow leaves are caused by insufficient fertilizer, you can add nutrient solution to the bottle when changing water, gently shake it evenly, increase the amount of oxygen, and promote root growth.

The water quality is not good

Reason: if the water in the bottle has been kept for a long time and has gone bad, the roots will rot and yellow leaves will appear.

Method: water should be changed every five to seven days in spring and autumn, three to five days in summer, and once every ten to half a month in winter.

5. Erosion of diseases and insect pests

Reason: if there are diseases or pests, the leaves will not be glossy, the leaves will be yellow and atrophied.

Method: you can go to the market to buy a special medicine to spray it, the dose should be small, you can spray several times.
