If your buds get dense enough that they rot, try silica at full strength next run, i bet theres little to none. The shit is seriously amazing. Great for people too. Not pro tekt thats formulated for plants im sure. But silica in general is so good for people. Better hair, nails and stuff like that. Snype i dont think it raises ppms/ec too much either. It sure as hell wont burn your plants up. Koolbloom also has been replaced by moab for me. I still like koolbloom though.
