Answer 1

Could be lack of nitrogen but in fruit trees the usual cause, if you are not over watering, is clorosis. This is an iron deficiency and is treated by using a cleated iron supplement applied on the ground around the tree. The typical look of a fruit tree suffering from iron clorosis is yellowing leaves with green veins.
