I pretty much use them all around , i use the A and b, veg ignite, carb boost, root nectar for veg then i add the bloom boost, and the pk heavy since its the old alaskan pure, And then use fox farms cha ching powder for the trichomes bc is a super duper magic potion it seems. Thats the one thing i wont let go of. I dont use the fullife or the crystallic or the flavor enhancer. And ofcourse i use calmag. I think im gonna try a different root booster next round. What do u think of the roots in the pic, do i need a better root booster
