Does anyone have an answer to this? I'm dosing with what I believe to be a pretty darn good translation of the numbers from the first post in my 29, with the sulphur obviously being lower, and the K+ from KCl being a little fuzzy. Is there anything at all to the SO4, or is it just filler and an easy way to get more K+ into solution?
