by looking at this and you saying the plant is a 12 week is probably pretty close to the plants life, i would check the tricomes from here on out though, milky/cloudy trichomes are what i go for, the amber tris are ok but usually amber means the thc is degrading and wont be as strong. so far your doing an amazing job, this looks pretty tasty for sure, great job and happy harvest in a few weeks

Check the trichomes and see for yourself. Usually the breeders say "x amount of time till harvest" but most of the time its that + a week or two. The only way to know for sure is by checking trichomes and making the choice based on personal preference. Clear trichomes are still immature while milky are matured. You need to get a loupe or microscope and check the trichomes on the bud itself, dont bother looking on sugar leaves since those mature faster.
