yea i dunno, mine are getting close to harvest, and im starting to flush too. Im thinking like 1 week left on mine, harvesting at 55 days. its tough to tell when they are perfect. The buds swelling is tough to gauge by, topped plants swell less usually. Hairs are hard to go by as well, some plants get dark ass hairs and some dont. Trichomes are what most people go by, but is it cloudy enough? is that trichome amber or is that a piece of dirt? fuck i cant tell anymore
Theres other hints too, the plant starts showing signs of micro nute deficiencies, throughout the leaves, even tho your feeding it like a mofo. Sticky ass nugs is a good hint too.
I guess you just gotta judge it. and if in doubt wait a few days
