Bloom ferts I generally start on day 1 of 12/12. You will need N in the first few weeks, to help the plant survivie healthy to a later time when you deprive it and most recipes ramp up the P and K values while dropping the N as the weeks progress, eliminating it altogether by week 5-6
Tokudai Reviewed by Tokudai on . When to start using bloom booster? (pics) I've got a plant, about a week into flowering, and it's looking female. I've been giving it the high nitrogen fertilizer for now. I am wondering when I should start giving it the high phosphate fertilizer? The fertilizer I'm using is 15-30-15 so there's still some nitrogen in there. Should I start doing it next time I feed? That's what I'm probably going to do. Or should I wait until I see buds forming? I can post more pics if you'd like. This is my plant that I had a long time Rating: 5
