Group,

Is there anyone here who uses k2so4 in water to fertilise. I tried to
prepare some, first mixture couldnt get 8 tblspoons to dissolve in 400 ml,
reduced it to 4 tbsp but i still have to shake the bottle before i use it as
it seems to separate after being left for a while.

Anyone else have this experience or any tips?

Ideally i wanted to be able to dose 1ppm K per ml of solution in my 160
litre. Currently i can only get .4 ppm per ml.
