Yes you do need to use all three nutes in grow and in flower phase. The grow and bloom phases use different amounts of those two nutes. The plants need a small amount of bloom nutes during the veg stage and when you put them into flower the grow nute amount is reduced but your bloom nute amount rises. I would recommend following the general hydroponics feed chart because they sell the three part formula as well. It worked great for me. I talked to an advanced nutrients rep and he informed me there three part formula was mirrored from general hydroponics formula. I tried not giving my plants the bloom nute during veg stage and all the new growth was twistedand deformed. Once I started giving the plants the recommended bloom nute dose all was well once the new growth kicked in. I am trying the advanced nutrients sensi A & B grow and bloom formulas now with great results plus it is pH perfect so I don't have to mess with my pH levels. Good luck!
Saggitaur Reviewed by Saggitaur on . Nutrient help please! Advanced Nutrients PH Perfect Base Nutrients I recently purchased the Advanced Nutrients PH Perfect Base Nutrients Micro, Grow & Bloom. And i read the bottles and it says your supposed to use all 3 nutrients at the same time, but i'm confused why would i use Bloom nutrients while i'm still in the veg stage? Am i supposed to use the Bloom while i'm still in veg? :wtf: Rating: 5
