Calcium Deficiency
Calcium deficiency is a common plant disorder caused by insufficient bioavailable calcium in the growing medium or, more frequently, by low transpiration rates that prevent proper calcium transport to new growth. It manifests as necrotic leaf margins, curling of young leaves, stunted growth, and in severe cases, conditions like blossom end rot in fruits. The disorder primarily affects rapidly growing tissues where calcium demand is highest.
