I used the powdered Koolbloom during the first half of flowering, then switched to liquid (powdered has nitrogen, liquid is a good 0-10-10). I'm not happy with this last harvest, but it has little to do with the nutrients in my opinion, and a lot more to do with the growing environment (too cold and humid, and I have to buckle down and get an RO unit).
This is, to date, however, my best indoor run thus far, so there ya go.
I picked up some
Big Bud, but too late to try on this last run. I'll use it on another run.
