Calcium deficiency vs. healthy plant-Beans

Symptoms
Older leaves show a dark green color whereas young leaves are pale green to yellow. The plants may wilt, older leaves can scorch and senesce prematurely. Plant growth is severely stunted. Pod and seed development is inhibited.

Reasons
Calcium deficiency (right) Calcium undersupply can often be observed together with Al and Mn toxicities in acid soils, where Ca levels are usually low. Calcium is easily available in the pH range 7.0-8.5.
