It has been 7 weeks since I switched to 12/12 and I am already seeing 30% amber trichomes and the hairs are about 50% changed. I am growing White Widow in FF OF, FF trio. Breeders pack said 56 day flowering time. I know you can't go by this, I see it as a guide. Could she already be about ready or is this way to early?
Without looking at the trichomes, I can tell there are still plenty of white hairs growing. Best guess would be a couple weeks.
