Yep, correct....I use Bio-Gro and Fish Mix during veg switching gradually to bloom, Topmax and heaven for flowering ....although I do still add a bit of veg nutes in with my blooming mix.....think you are supposed to use part bio veg with it, doesnt work good on own.
I sometimes put a ml or 2 or 3 in my topmax + bloom mix....sometimes I don't....I have several strains going right now...just finished 4 lowryder 2 that were the largest yeild for a lowryder strain in the 4 yrs I've grown them. I also add some Blue Mt. Organic Super Tonic....all of it has really increased my yeilds...is iT advisable to use Heaven and Grow together or no point, burnny burnny?
