Severe cases can cause stunted growth, a spindly appearance, [4] and yellow leaves which can eventually fall off of the plant. [5] The disorder is not infectious and if edema is the only problem, then the plants are safe to handle and the parts of the plant which would usually be edible will remain safe to eat. [8]

Abscission (from Latin ab- 'away' and scindere 'to cut') is the shedding of various parts of an organism , such as a plant dropping a leaf , fruit , flower , or seed .
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. Over time, the yellowing may even turn a pale white or the whole leaf may be affected. [4] Iron deficient plants may overaccumulate heavy metals such as cadmium. [5]
