GSA, Dosing All Ferts Same Day?
So lately I have been dosing all my dry ferts on the same day. I make sure to dose phosphate first, and anything containing iron last to give them sufficient time to disperse in the tank.
Problem is I'm starting to GSA on the glass. Could it be that because I'm dosing iron and phosphate on the same day they are precipitating out and lowering my phosphate levels? I'm not seeing any signs of iron deficiency, but I've read that GSA can be a symptom of low phosphate levels.
Any thoughts would be appreciated,
