The youngest leaves show chlorosis (yellowing), dwarfing and malformation. Visible deficiency symptoms include: [3] Chlorosis - yellowing of leaves; often interveinal; in some species, young leaves are the most affected, [4] but in others both old and new leaves are chlorotic; [3] [5] Necrotic spots - death of leaf tissue on areas of chlorosis;
Yellowing (Chlorosis) occur in the newly emerging leaves instead of the older leaves and usually seen in the interveinal region. Fruit would be of poor quality and quantity. Chlorosis occurs in younger leaves because iron is not a mobile element, and as such, the younger leaves cannot draw iron from other areas of the plant.
