Purple lemonade/Gelato auto

There is some volatility in autoflowers -- e.g. an "XL" version came from somewhere, maybe your plant is one of those genetic lotery winners without being selected for the trait. Another possibility is that it is actually a photoperiod plant. If you see absolutely no hint of flowering, this may be the case. If set up to handle it, go ahead and give it 12hours darkness for a couple weeks... if not, give it another week or 2 and see what happens... if still vege it's getting way more likely to be a photoperiod. Can prune it back if doubling in size from that point is a problem. lol, make sure to prune it back if it is a photo, because you got another ~9 weeks from 12-12.

Tbh, i would wait at least for day 75, so another week. If you wait untill you are at least at 5% ambers you can be sure that more clear cristals will be turning milky and overall potency will be stronger. Got some beautifull purples there btw. If u wanna harvest now u can do it, but your trading some serious yield for time, and you can ve sure its gonna be a head high if you harvest now, give it 1/2 weeks if u want a more mixed high, body and head, and about 3 weeks or+ if you want a full sedative high. I'm trying to keep it short but i think i got the point across to u.

Don't fret! Your plant is in great condition. Cannabis color can fade towards the end of its lifecycle. This is a great indication that your plant is using up all if its extra nutrients stored in the leaves as it nears the end of its life. Trichomes on the Sugar leaves will be the first to turn Amber. However, the process is not as "clear" (pun intended) as previously thought. Research shows that cannabinoid biosynthesis is still occurring faster in light amber trichomes than THC is degrading into THC. This means only when trichomes turn a solid dark amber does THC start converting quickly to CBN. In short, you want to limit the amount of clear you are seeing, and maximize the number of solid white/light amber trichs. The percentage will differ among cultivars, but to answer your question, I would not worry about letting these go at least another week, possibly more. You take brilliant photos of your trichomes, try to focus on the buds and don't worry if some sugar leaves are dominantly amber trichomes. If you want more information on the most updated info, this article and specifically Dr. Photons reply should shed some light on an otherwise *unclear* topic.https://www.cocoforcannabis.com/community/main-forum/when-to-harvest/
