I have a bag that contains Ks2So4 (Potassium sulphate?) mixed with MgSo4 (Magnesium sulfate). I don't think I need to be dosing them since I'm using Seachem Potassium and my GH is already a bit high. Should I try dosing a small amount of phosphates? My nitrates are around 20-40 ppm. Should I be aiming for ~2-4 ppm of phosphates or is that too much for how little plants I have?
