Citrus - Chlorosis

Symptoms
Symptoms always start at youngest leaves with yellow green, later pale yellow interveinal chlorosis. Veins remain green. Sometimes leaves look like a mosaic or net, because also fine veins stay green. With ongoing deficiency veins become chlorotic, too, and symptoms extend to older leaves.

Reasons
Iron deficiency on leaves of lemon. Please note that this symptom may be a sign of HLB/Citrus Greening, and not a nutrient deficiency!
