I recommend potassium sulfate mostly for indoor use (for all kinds of seedlings and such), and for outdoor muskmelons. I'd rather use wood ash for outdoor tomatoes (if the pH weren't an issue), but potassium sulfate will provide them with potassium. If you've already planted, I'd use potassium sulfate. Potassium sulfate can also help to reduce the symptoms of transplant shock.

I like to use peat moss to balance the pH with the wood ash, these days. I'm not sure what it reads on a soil test, but the plants grow in it.
