NUTRIENT IDENTIFICATION SYMPTOMS SUGGESTED PRODUCT Nitrogen Yellow-green, uniform discoloration of foliage. Older, lower leaves are affected first. Plant growth is stunted. Rhizo Caps Phosphorus Plants suffer from growth retardation and sparse foliage. Older leaflets show interveinal chlorosis and necrosis. Light brown necrotic blotches coalesce along the leaf margin. PSB Plus Potassium Irregular yellow border around leaves. Potash grow Sulphur The upper leaves turn yellowish-green or chlorotic. Older leaves remain green for longer periods. Under severe deficiency, all leaves may become yellow, resulting in stunted growth. Sulphur Caps Boron Upper leaves turn yellow and become mottled with small, brown necrotic spots. Leaf margins are bent down and internodes are shortened. ALP Copper Several leaf blades in the upper and medium height show yellow discolorations, starting from the leaf margins and proceeding toward the leaf base. ALP Iron Beginning interveinal chlorosis of the upper, new leaves due to iron deficiency. Chlorosis starts on the leaf base and proceeds along the midrib. ALP Manganese Light green interveinal chlorosis with striking green veins. The proceeding chlorosis gives the leaf a mottled appearance. ALP Molybdenum Several leaves of different ages show a light green to yellow chlorosis, spreading irregularly over the leaf blade. ALP Zinc Younger leaves of Zn-deficient plants show interveinal chlorosis and necrotic brown leaf veins. ALP
