Manganese deficiency

Manganese deficiency is seen in citrus as interveinal chlorosis, similar to iron deficiency. The midrib and other veins are green and the other areas of the leaf are yellow, but in a mottled pattern. The green vein pattern extends out into the chlorotic areas of the leaf and is less defined than iron chlorosis.
