Looking at your grow conditions and without seeing a microscope picture of the trichomes, I would say you give them a last light feed on the week 9 of flower and start flushing by week 10, aiming at 20-30% runoff each time, for 1 or 2 weeks, so they can ripe those buds even more. Keep an eye on the buds and trichomes as the leaves yellow, for they can be ready before you finish flushing. Take a note on the smell too, it's a good indicator, as it starts to decrease, they are ready. In the last week the smell should be 3x, 4x times stronger and then it starts to turn to a more fermented scent, with lower intensity. Got that from a Ed Rosenthal book and it's a true thing. Have fun growing! Tchau, do Brazil! =) ,

8 to 10 weeks of flower is where most strains are ready. in absence of a microscope / jewelers loupe, the calyxes swelling and hairs going red is a good sign of the plant been ready.

Hi to me your Girls look pretty ready. Just do it like Hoffguy told, to see how far you are. For me they look very near to harvest because she changed to " autumcolours" and the Hairs turned over 75 percent to orange/ brown.My guessing would be 5-8 Days for the PH1. The Buds will Maturate very nice in that time. In the comments i will let you a link to a sit where you can compare your girl with other" nearly ready to harvest" palnts. but from that point you can just doing things right.by my eyesight the trichomes look milky. But just check it by yourself, because i just see a picture. Happy Harvesting

Hey there! So the only way to know when your plants are at peak ripeness, is to use a pocket microscope or jewelers loupe to look at the trichomes (crystals) on the buds. What you want to look for is Cloudy/milky trichomes that is when they are at peak resin production. there are 3 stages of the trichomes life, Clear-to early don't harvest yet Milky/Cloudy-peak production and amber- it is past peak and the THC oxidizes into CBN and can produce somewhat of a fake couch lock feeling. So it best to harvest when it is as close to 100% cloudy but that is very hard to do so some people go a little on the early side and chop at like 90-95% cloudy and 5-10% clear. Some people go a little longer and the the same but with 5-10% amber and sometimes if you wanting a more couchlock like feeling some folks will go 30% amber it up to you on that part of when but as long as you get almost all of them when cloudy your good👍 Happy Growing!!
