Why are there black spots on the leaves of hydroponic green radish?

1. The temperature is too low

Reason: The temperature cannot be too low when growing green ivy, especially in hydroponic cultivation. It is easy to freeze it. Once it suffers from frost damage, the leaves will have black spots or become withered.

Solution: The temperature of the maintenance environment needs to be increased, and the frozen leaves need to be cut off as soon as possible. When the indoor temperature cannot be raised, warming measures must be taken.

2. Hot and stuffy environment

Reason: In the summer when the temperature is high and in the winter when the room is heated, if there is no ventilation in these two stages, it will show adverse symptoms, the most common of which is the growth of black spots.

Solution: The hydroponic green radish needs to be moved to a place with good air circulation, such as a balcony, outdoors, etc. In winter, you just need to open the windows more often to let it ventilate.

3. Improper lighting

Reason: When caring for it, it should not be exposed to strong light, but it should also not be placed in a dark place, otherwise black spots will appear.

Solution: The plants should be exposed to mild diffuse light, especially in summer, and reasonable shading measures must be taken. If the lighting in the maintenance location is poor, move it to a location with good lighting.
