Honestly I dont remember off top of head(its been a few yrs since I used them) but as with most nutes, I would normally start off at half strength and see how plant reacts. If it looks fine on the next app I would bump it up. And yes I did notice a difference(but there were more things changed than just adding those nutes) and now I dont use them as I grow organic and still get very healthy harvests. So I wouldnt say its required by any means, never hurts to try new things. Good luck, Numb
I'm flowering in a bubble bucket right now. 3 gallons of water. 24ml micro 48ml bloom 15ml flora nectar 15ml liquid kool bloom 15ml hygrozyme 15ml diamond nectar Everything's working just fine. Flowers are growing fast and dense. PPMS on the fresh bucket I just mixed this morning were about 1700-1800.
