What happens when plants lack CALCIUM?

Answer 1

Unlike other nutrients, lack of calcium generally affects the growing points and young leaves of the plants.

The young leaves are often twisted or wrinkled. The growth is reduced with tiny black spots appearing

around the mid-leaf area of young leaves and on the tips of very young leaves. In some cases, these black

spots appear on the growing points. Abortion of flowers or flower buds is common if calcium is unavailable

during flowering. During fruiting, lack of calcium can result in fruit cracking, water soaked tissues or

blossom end rot
