I bought some Muriate of Potash as a Potassium source. I've read before
that this is a usable source of Potassium. All I need to know now is how to
dose it. Here's some info from the back of the bag:

0-0-60
Guaranteed Analysis
Soluble Potash (K20)------- 60%
Derived from Muriate of Potash.

Any suggestions are greatly appreciated. Thanks.
