What can cause white spots on the eggplant
To solve a particular problem, it is very important to know its root cause. Very often, white spots on the leaf plate are formed due to the attack of pests. Also, many of them lay eggs in the ground, so before planting, it is very important to disinfect the planting hole. You also need to carefully examine the foliage with a good magnifying glass in bright light.

Fourth reason
Lack of potassium elements.
Fifth reason
