DWC going well about to go to the growstore. I'll be straight with the Cal-Mag I already bought (rinsing the tablets work well, til their not slippery/slimey anymore and I don't know if vegetarian or generic is better then any of the various brands.) Also been using peat moss tea and boron and native sulfur from a mineralogy kit from the 1950's. (I told you I was thrifty.) I would've gone to growstore already if not for recent weather and other conditions. Btw I'm loving Cancom, their me and my grow partner's special helper, making us feel like we're not in it alone. That's been invaluable to us and we'll always do anything to help this site and the people who keep these resources up, and we'll do it any way that we can, just ask. =P
