Potassium deficiency is characterized by a cupping or “puckering” of leaves and affects older leaves first. Leaf cupping is usually accompanied by a slight marginal chlorosis, with the leaf margins dying especially at the tip in severe cases. Leaf symptoms are accompanied by abnormal fruit development, cucumber fruit often developing a brown or spotted appearance and melons often developing abnormal flesh texture and off flavor.
