That is normally available in 275 gallon cubes. However, it too is very alkaline, risky to spray on at low volumes and not irrigate in immediately.
I have found a sprayable source of potassium sulfate at a decent price. I was wondering why you prefer potassium nitrate. I know nitrate is a saltier product but has slightly less chlorine.
