Here in Iceland where I live is quite hard to get access to powders for fertiliser making
What I have managed to source is Potassium Nitrate (strangely, that was the easy part), Magnesium Sulphate and I have some CSM+B on order via Amazon
I have been complately unable to find any Potassium Sulphate but I have been able to find Potassium Carbonate (not Bicarbonate)
The water where I live is quite soft. KH is around 3dKH
My question is - given the soft water, can I use the Potassium Carbonate as a replacement for Potassium Sulphate as long as I keep an eye on the Alkalinity?
Any advice would be greatly appreciated
