She can be done quicker than expected , due to many factors but I’d give atleast a week or two longer, if you have a magnifying glass or microscope , look if the Thc glands are milky or Amber

Yes use jewellers loupe and when they get to this stage I always check the trichomes.

Best bet would be to get a Jewelers Loupe. They are less than $20 and allows you to see the trichomes. You usually want to harvest when -roughly- 30-50% are amber. I harvest my Sativas before 20%, though. Other options are a microusb microscope you can buy for also less than $20. These tend to break at the power connector(microusb)but give a much better view. It's very hard to tell by just looking at it. Those two options will have you looking at trichomes as if your eyes were touching them, though.

Some of those photos look close but by close I mean two weeks maybe. One plant is further behind and may take around 4 weeks till ready. Looks sexy though, don't harvest her too early! 🌱👍
