Chlorosis on an apple tree.
Is it safe to keep spraying my tree every 2-3 weeks to correct the chlorosis with the apples on it? Will this affect the edibility of the apples?

I have sprayed my apple tree with chelated iron once several weeks ago. I thought I would spray it once more since it still looks slightly chlorotic. I have slightly alkaline soil and have added sulphur this spring and in the past. The tree hasn't shown these signs before, but we had a very wet fall and a wet spring which seemed to promote the chlorosis ( 8-9 inches this spring ). I wasn't sure if I should spray again since the apples are developing. It doesn't list any specific fruit bearing trees on the label. It has no mention of anything about spraying while there is fruit. I know the spray is a short term fix until I get the pH right.
