I have an iron deficiency that began when I flipped to flower about 10 days ago. I have been using Iron Chelate 10% plus also foliar spraying every day but the problem has not fully resolved. I do not know how much of this product (see attached photos of product) to use but am being careful not to use too much. I have read that Iron is immobile and takes awhile to move up the plant. And, I think I am seeing some improvement. Anybody have experience with this product or with iron deficiency and could advise me on how much of this product to apply to fix problem? and how often I need to re-apply?
I do not believe you have an iron deficiency. This is what an iron deficiency would look like. This one was caused by a build up of high bicarbonates in my water. This pot was on its 4th cycle. Note the leaf color. An iron deficiency is the only one that once fixed, the leaves will turn green again.
