Deficiency of Zinc

There is probably a deficiency of Zinc. Young leaves are reduced in size (often called "little leaf"), up to 95% in severe cases of Zinc deficiency. Young leaves may exhibit interveinal chlorosis and internodes remain very short causing a rosetting effect. Tufts of abnormally small leaves or shoots are called rosettes. Chlorosis of young leaves may not be the dominant symptom, but leaves are often narrow with wavy margins or one side of the leaf may expand faster than the other side resulting in a puckered leaf.
