I have been using it since I came across the original thread, though I erroneously added 4 parts K2SO4 instead of 2 for the first couple of dosings, which is why I posted my last post
I literally added 1.00:.75:.25 with dry ingredients, gave me a lot more K+ than I wanted. I think N crashed as a result.
Growth seems to be ramping up a little...it's too early to tell, I think.
