Scott-

I've never used Sul-Po-Mag, but apparently it's a good source of Potash. It's 0-0-22, I believe. Hermitian proscribed very small dosages of the Sul-Po-Mag as a substitute for Wood Ash. Is it easy to overdose plats with too much Calcium or Magnesium? I haven't heard of that as a common problem, though I have read threads where folks were trying to amp up the amount of Epsom salt, which also has a lot of magnesium, and the result wasn't good. If no one else chimes in here, I'll probably just keep the lime dosage quite low, perhaps around 1 cup per 2'x2'x16" "cube."
Thanks,
-naysen
