ferric phosphate which is formed when iron and phosphorus meet is usable by plants, its actually in a lot of terrestrial fertilizers. HOWEVER, it requires a lot of enery for the plants to use it, and it takes a long time for it to degrade enough for the roots to pick it up.

that being said i would alternate my dosing days to prevent this, what kind of light ? co2 if anyt do u have?
