I'm running a hydroponic system, so I've nothing to say about soil amendments and such. However, I just finished experimenting with their 3 part deal: Cha-Ching, Beastie Bloomz and Open Sesame.
There are several 4x8 ebb n flow tables. (The herb grown was all Purple Kush. It's drying now, so no word on flavor/aroma yet.) Cutting Edge nutro was used thruout. During flowering, table 1 was given Monster Bloom early and Overdrive late. Table 2 was given the 3 part Fox Farm nutes: one in early flowering, one middle, one late. Table 2, with the Fox Farm products, finished faster, got more purple-y, and produced fatter, denser nugs than table 1. I'll be using these products again, next time on the whole flowering room.
