Symptoms
The interveinal areas of the leaf become chlorotic, the main veins and a margin around them remain green.
Older leaves are affected first.
Reasons
Magnesium deficiency
Manganese deficiency develops similar symptoms, but starts from younger leaves and at first even the smallest veins remain green.
Pepper - Chlorosis
Symptoms
A faint, light green marginal chlorosis is visible. With ongoing deficiency the chlorosis will develop towards the center of the leaf, but the main veins and a margin around them will remain green. Normally the symptoms start at mature leaves.
Reasons
Magnesium deficiency
Iron and Manganese deficiency cause marginal and interveinal chlorosis, but the symptoms start on young leaves and at first even the smallest veins remain green.
Pepper - Chlorosis
Symptoms
A light green marginal chlorosis is visible. Normally the symptoms start at older leaves.
Reasons
Magnesium deficiency

Pepper - Chlorosis
Symptoms
A light green marginal chlorosis is visible. The chlorosis starts to progress towards the center of the leaf, but the main veins and a margin around them remain green. Normally the symptoms start at mature leaves.
Reasons
Magnesium deficiency
Iron and Manganese deficiency cause marginal and interveinal chlorosis, but the symptoms start on young leaves and at first even the smallest veins remain green.
Pepper - Chlorosis
Symptoms
The interveinal areas of the leaf become chlorotic, the main veins and a margin along them remain green.
Older leaves are affected first.
Reasons
Magnesium deficiency
Iron and Manganese deficiency cause marginal and interveinal chlorosis, but the symptoms start on young leaves and in the beginning even the smallest veins remain green.
Pepper - Chlorosis
Symptoms
Interveinal leaf areas become chlorotic, 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.
Reasons
Magnesium deficiency vs. Optimum (left)
Iron and Manganese deficiency cause marginal and interveinal chlorosis, but the symptoms start on young leaves and in the beginning even the smallest veins remain green.
Magnesium deficiency made worse by
Sandy soils
Acidic soils
Potassium rich soils
Soils receiving high potash applications
Cold wet periods
Magnesium is important for
Increases photosynthetic activity maintaining good growth for high yields
