Grapey Walter! 3rd grow

Although most autos are done between week 9 and 10, it is not always like this. I have personally seen autos finish in 8 weeks and 12 weeks, and everything in between. Just let id to its thing, it is already flowering. Also some trainings can delay flowering, like TOPing, defoliation, etc.

You could maybe take a few leaves, over the next week, without too much setback, but I really wouldn't recommend it with how far she's into flowering. - If you absolutely have to do it, don't take more than a single leaf a day, preferably 1 every second day. What I'd recommend instead, is harvest her in stages later on. So you take the branches that are ready, and let the rest grow, and continue till you're satisfied they're all done.That'll probably give you a better yield than starting defoliation at this point in time.
