can i premix KH2PO4 with K2SO4 ?

i premixed KH2PO4 with K2SO4 in a 250ml bottle and after a month i see some sort of white rile on the bottom. never had that when premixing KH2PO4 with KNO3.

what kind of rile? does it get away if you shake the bottle?
should not be a problem. use distilled water, and add some excel to it to prevent molding. keep in the fridge the mixture if you can.

Make it in smaller batches so you use it up before stuff starts to grow.
