Thanks, Tom! Just the numbers I needed. Anyway, I made the solution, and 
boy, is it messy! Little floaties, suspended bits, and undissolved junk... 
I suppose I could filter it, if need be. Would you or anybody happen to 
know anything about the brand Espoma? Is their "Sulfate of Potash" equally 
sooty? I almost ordered it on-line, but I can't find much info on it.

Eagerly waiting to see less yellow, more green ;-).
