I got 3 summer grows in this year. Had root bound on the ones in the blue tubs so I had to cut the bottoms out of their 5 gal. buckets and placed them in to 17 gal tubs. I couldn't do a full transplant because they were in full flowering and a few weeks til harvest time. 2 out of the 3 plants re-vegged so they took longer but the up side was I yielded almost double in quantity. In all grows I used Blue Planet 3 part micro nutes and flushed all plants with for 3 weeks with Sugaree. I found out about Sugaree on the 3rd grow. Too bad I didn't find that stuff earlier because that stuff gave my plants such a sweet killer smell and taste. All 3 grows were the same strains but I could tell the difference on the last one. So much more tastier. It has Soluble Potash (K2O) ..2%.
Derived from Potassium Sulfate. My soil was strickly Fox Farm Ocean Forest Potting soil on last ggrow and will be from now on. Love that stuff. The first 2 grows I mixed the sub-cool Super Soil Mix). It was much more exspensive to buy all the ingredients than just buying the F.F. soil that worked the same give or take. Couldn't tell the difference. Layered the bottoms with black cinder rock for drainage and grew to my hearts content.
