Mixing in DI water Calcium nitrate tetrahydrate, K Phos Monobasic, and Mg Sulfate, about 2% each. I am not sure if it is the sulfates or the phosphate that causes solution to get cloudy with ppt. Tried also to lower pH from initial 3.8 to 3 or so with dil sulfuric. Any one know what is causing the cloudiness?
I still have to add KNO3 and K2SO4 in even smaller qtys but I stopped here as no need to proceed with a bad/turbid solution
