Therefore, if you notice that some leaves become slightly lighter, it is urgent to identify the cause of this and fix it, otherwise the plants will soon be able to curl the leaves that will lead to their death.
Often pallor and leaves twist eggplant says that they do not have enough light. If potted plants are in the back of the room, then move them closer to the window. Seedlings in any case should not be left under direct sunlight, otherwise the inevitable burns.
