I have recently made my first batch of macro and micro ferts using dry fertilizer and R/O water. I followed the PMDD+PO4 method in the EI thread (PMDD style EI). My macros will not stay in solution. Is this normal? i was thinking of not mixing in the GH booster and just adding that at water change. Should that help? Or does the mono potassium phosphate and the potassium nitrate just not stay in solution? Maybe there is something i have misread or missed. Please help. thanks!
