I've tryed a lot if different base nutes with my A1 additives.. In veg I've had great results with Flora Nova,Iguana juice, Mother Earth tea, & another 1 I can member I mixed them with A1 & had great results.. In bloom I've tryed Connie A&B, Mother Earth tea, & flora nova.. But I've been rocking the full A1 line up G.o.D shot me the Grow A&B & the bloom a&B I've been using that with similar results like with Connie..
When master blaster I've used 2tsp per 5 gal but that a Lil over 200ppm's so next I'm gunna try 1.5 tsp per 5 gal or maybe even 1tsp per 5.. It's very strong stuff & u don't need that much.. My ppm's in veg maxed at 400 & in bloom I never went over 1000 ppm.. I kept it mega light
