If possible, add some more chelated iron. If you can't find any,
I would suggest making a solution of an iron salt in water in which you
have already dissolved disodium EDTA, and using that to increase the amount
of iron.
There seems to be quite a bit of copper in this mix, so you will
have to be a bit more careful not to overdose with it.
