Currently: Athena Blended (Bloom A&B, PK) + GH CaliMagiC & Armor Si
Previously: FoxFarm trio; GH Flora Trio + CaliMagiC, Armor Si, Diamond Nectar, and Floralicious Plus
All used in coco + perlite. Best results to date, the GH trio and extras. Worst results, the FoxFarm trio; i was always chasing problems.
Next up: trying FloraNova Grow and Bloom, CaliMagiC (if needed) and Armor Si (will still use) and Floralicious (maybe, since i still have it). I personally love GH products but the trio + extras was like 6 or 7 bottles at any one time! If i can cut that down to like 2 to 4, that's doable for me.
