Why would you expect to flush week 5. First flushing is broscience no one who's grown for any amount of time flushes. I have we mostly all have flushing has no added benefits. Flushing I assume you were going for 2wks afterwards. If you had a auto that wouldnt be done in 7 weeks. Photos will never ever be done in 7 weeks. I dont think I've ever seen a breeders flower time listed at 7 weeks. When growing photos always add 2 weeks to breeders harvest time. Flower time doesn't start at light flip to 1212 but rather once plants actually transition into flower generally taking near 2 weeks. If that's a auto look to harvest at day 100 more likely around day 110 to 115. Good luck bud awesome job so far
Hairy are pistils that's normal
Imo looking at trichomes under a microscope only allows you to see a tiny portion of plants. There are millions if not billions or trillions of trichomes on each plant. Looking at a tiny portion of them can be misleading for majority of trichomes, especially if you're itching to harvest already. Top buds closest to light and sugar leaves will amber sooner and be misleading. You want the plant as a whole to be mature enough to harvest not the selective trichomes you viewed. All cannabis plants look the same when ready to harvest, without looking at trichomes. Most photos will run 12 to 16 weeks more up to 16 fewer at 12. What you want to see from photos and autos are change in pistil color, those white pistils will go orange or brown maybe red, after that those pistils will start to curl in towards the buds or calyx, Calyx's are what buds are comprised of. Once those pistils change color and curl over the next 2 to 4 weeks calyxes or buds will start to swell, during this time is when beginners will generally harvest, early. only once calyxes fully swell causing those curling orange pistils to recede into them is the plant ready to harvest. You can look at trichomes then, but you wont need to because the plant will be done.
