When should i harvest/chop down?

That looks like it has a while to go.The simple way we learnt back in the day,and I mean back in the day not several years ago.In the 90s we were told you can harvest when two thirds of the hairs are brown and all yours look white so I guess you've got a couple of weeks left.You can see if the trichs are clear,milky or amber on a half ecent phone camera.Is it a dreaded auto,ha.Autos can go on for weeks longer than the breeders claim.Yoiu want to give her at least another week but those hairs will take agt least 2wks to brown.You can do her in a week if you want.I doubt you'll notice the difference between 1wk and 2wks,I doubt you'll notice the difference with the effect.THC could be a touch higher but you're not going to notice.Keep an eye on those dead leaves,its where the mold starts.If a dead leaf is touching a flkower then remove the leaf.Get hands on and check inside those buds and look for white cotton like webbning,if you see any remove it as its mold.
