Nzmk902answered grow question 4 years ago Ya man what i found when u see those white hairs. Id be kicking it into bloom.... ive read u can veg a week or 2 longer... i tried it... personally i think i missed a crucial time to add more bud juice. Lol. But thats my first attempt and what ive noticed.... soon as i see the split to see if its a female and they start getting hairs. Im gonna hit it with bloom schedule..... but thats my personal opinion... n it was my first time grow... but like advertised it says 3 weeks start to bloom... should kick it into bloom in my opinion... i tried to stretch 5 or 6 weeks veg. And in the end my buds werent full... i misjudged the time..... hope it helps.
