I'm using Advanced Nutrients Sensitive grow and bloom coco. What day should I switch from grow to bloom? Have 6 between days 20-25, a few have shown their sex already. Wanted to give grow nutrients as long as I can cause they're small. I have read somewhere that you should give grow nutrients for 6 weeks, is that correct? I was thinking of going 5 weeks, but if 6 is better will do that. I used ffof for 1st grow so didn't use base nutrients. Any help would be much appreciated.
