macro ferts crystallizing?
So I made a solution of macro using zorfox calculations and after I had it in the fridge for a day or two, it started to crystallizing at the bottom... Is this normal?
Here is the mix I had done for the macro
500ml spring drinking water, 20 ml per dosing every other day
KNO3 - 104.2 gm
KH2PO4 - 15.9 gm (I double this to help prevent GSA to around 20-30 gm)
K2SO4 - 42.4 gm
This is to dose for a 90 gallon of water.
So can anyone tell me why my mix is starting to crystallizing ? If I dose the crystal, will it dissolve in to the water?
