Magnesium deficiency-Chili

Symptoms
Interveinal leaf areas become chlorotic, while the main veins and a margin along them remain green. Necrotic patches occur on the leaf margin and spread toward the leaf centre. Older leaves are affected first. With severe deficiency, leaf blades are deformed: older leaves show a hook-like shape, young ones are vaulted down. Total leaf size is reduced. Growth, flowering and fruiting are stunted. Iron and manganese deficiency cause marginal and interveinal chlorosis, too, but the symptoms start on young leaves.

Reasons
Severe magnesium deficiency. Magnesium is needed in large quantities. Undersupply can be induced by excessive potassium.
