yes, definitely harvest by trichome, jewelry loupes (40x) are okayish and dirt cheap i got mine for $4, 100x magnifiers are also like ~$10 and fiddly but work better. You can get a usb microscope for like $15 on amazon that's amazing if you have a tablet or something you can take to the grow room. Apart from that, AFAIK "max THC" is when the trichomes are ~25% amber with the rest fully cloudy and erect.

Hey bro as some commented you choose based on your preference, at home i make sleeping aid mainly so I let them go for a wile more, and assure a more couch lock effect, narcotic, here i send you a scheme of the milestones in this matter, note that some Like in-between this steps, you have to experiment and find out your own, checking the trichomes with a magnifying lens. In my case i use atached to the mobile phone camera, a cheap one from amazon.

A - 40% of hairs have darken, trichomes are half clear and half cloudy : Produces a more energetic effect, and buds tend to still growing in size.

B-50-70% of hairs darken, trichomes are milk / cloudy, you get the most intense high, with most euforia - pain relief vibe.

C- 70-90% hairs have darken, trichomes are major ambar and turning, you get more CBN less THC and a more relaxing / narcotic / couch lock high.

So in my case i go for the C. Hope this adds to your question somehow.

Good luck! Happy growing.

If you don't have a loupe, you can wait until the calyxes swell and then give the buds a week, this should be around the time the thricomes are mostly cloudy, the hairs will recede and many (if not most) will have turned yellow (or orange)

I would guesstimate about another 3-4 weeks. Patience is really important at this stage. You can go by breeders timeframe or pistol colour but both can be very inaccurate. The most effective method is to get a jewellers loupe or a microscope, if you have shaky hands like me lol, and inspect the trichomes. When you see cloudy heads changing to amber/gold/brown, it's reaching peak harvest. So that would be the max THC possible. After the peak window, which is about a week, THC breaks down into CBN and gives more of a couchlock stone. Happy growing and peace. :)

It depends on what you are looking for. For the highest thc then you want your trichomes to be all cloudy. I personally chop my plants at the very first sign of Amber trichomes. I use my smartphone and take pictures in zoom and then look at them for amber.. when you see amber you will know.
