beastie bloomz is what you need, i use open seasme before flowering starts, when i am in flower i just use the beastie bloomz, it works great and your plant is at that stage to go ahead and do the beastie bloomz, since you are already in flower hit it with the beastie, big buds later. as far as the pure bloom use half of what you been using for the first few feeds then use just beastie, greta stuff i can say enough
