Is she ready for harvest?

It's hard to see the trichomes, but they look mostly transparent and there are no visible amber colored ones. Best to wait another week and check in the mean time.

Depends how you like your smoke and/or if you'd like your flowers to have a chance to bulk up a bit... Judging by the photos, you got plenty of time left to test your patience and skills of observation, maybe even a bit more flushing to do? Personally I'd only go 1-2 more weeks max and shoot for an amber rate of 10-15% average across the plant. A good tip for figuring out how you like your trichs to look is to shoot for an amber rate of 15% on the area that is most mature on the plant as the plant never matures evenly. Then you can sort buds post harvest after scoping them and put like trichs with like trichs. Test smoke each and make notes of the trichs of the ones that do you right. If you find that 15% is too much of a couch-locking experience, you can always dilute the more mature buds with less mature ones in a grinder to strike balance.

Yes

Depends on how bad you want to smoke it.

Hey there! I would wait atleast a week. As you can see in the photo, your trichomes is still clear somewhere. You would like to harvest when either the trichomes are cloudy/milky or when some of them starts to be amber. The THC is most present when the trichomes are mily, but if youre aiming for more of a couchlock, you want around 5-10% of the trichomes to be amber. Hope you'll have a great harvest 😎

Hello Bluecake, You trichome picture is not really clear but from the overal look from your plant and the trichomes that I can see I would say wait 1 more week till harvest! Happy Harvest Buddy! 💚
