Iron deficiency in Apples

Symptome
Symptoms always start at youngest leaves with yellow green, later lemon yellow and pale yellow interveinal chlorosis. Main veins still remain green. At strong deficiency veins become chlorotic too and necrotic areas appear near leaf margin. Severe deficiency produces symptoms at older leaves too. Often young shoots of one tree are different in grade of damaging.

Gründe
Severe Iron deficiency May be confused with magnesium deficiency. But magnesium deficiency produces symptoms at older leaves first.
