It still has some time left. Keep track of trichomes with a jeweler's loupe and the earliest you want to harvest is when all the trichomes heads are at least cloudy/milky.
If you want a couch-lock effect, wait until the trichomes are mainly amber. About 50% amber and 50% cloudy will give you that feeling.
I hope this helps.
You'd need to get a much closer picture of the trichomes... try zooming in as much as you can to take a photo... then you can zoom in on THAT photo... if the trichomes are all cloudy with some of them turning amber, you're ready to harvest.
удачй!
