Deficiency of Manganese

There is probably a deficiency of Manganese. Young leaves of Manganese deficient plants exhibit interveinal chlorosis with a relatively wide area of green associated with the veins, but leaves do not become cream color. Leaves, shoots, fruits or stems may be contorted, and plant parts may be reduced in size or have necrotic spots that are tan or gray. Interveinal necrosis or necrotic spotting is also typical of Manganese deficiency in some species. Manganese deficiency is very common for plants grown in alkaline soils.
