Magnesium Deficiency of Solanaceous Crops
Return to Physiological and Nutrient Disorders
Magnesium deficiency symptoms are characterized by interveinal chlorosis (the leaf veins stay green while the regions between them turn yellow), typically on older leaves. As the deficiency progresses, the interveinal chlorosis will move up the plant. Some micronutrient deficiencies can have similar symptoms, but they generally appear on newer growth
first. Magnesium sulfate (also known as Epsom salts) can help prevent or alleviate this deficiency.
