What are the old yellow leaves of hydroponic spring feathers?

The leaves of hydroponic plants turn yellow, probably because nutrients cannot meet the needs of growing plants. Under normal circumstances, the cultivation water in the basin should be replaced once every two months, and tap water can also be used, but it should be noted that tap water should be placed for a period of time before use to keep the root system temperature stable.

Hydroponic flowers are mostly negative and neutral flowers suitable for indoor cultivation, and have their own requirements for light. Your ivy is a shade-loving plant, so you should shade it moderately; It can also grow normally under indoor scattered light. It is very important to ensure the normal growth temperature of flowers, and the root system of flowers grows well in the range of 15-30 degrees.

Attention should be paid to distinguish the color of the root of the flower to judge whether it grows well. The whole root or root mouth with suitable light and temperature nutrient solution concentration is white. Please note that it is forbidden to add too much nutrient solution to shorten the interval between adding nutrient solution.

During the growth of hydroponic flowers, if water drops are found to seep from the tip, the water level should be lowered appropriately to expose more roots to the air and reduce the soaking ratio in water.
