humboldt nutrients

ive used bushmaster, purple maxx, and gravity. they are all awesome. i feed bushmaster at the beginning of flower. in the 3rd week i foliar spray ever 3-5 days until week 6 with purple maxx. then they get 2 feedings with gravity, once in week 6, once in week 7.

they are hot nutes, so i go under the reccommened dosage.

what does bushmaster exactly do? i remember hearing it but forgot... did you see any color hues of purple in your plants or incrased trich production? also whats gravity do? thanks
