Hi there
As below really, get yourself a cheap jewels loop and check the trichomes to see what stage there at..
Dont look like u got long left id say 👍
Best of luck bro 🌱
Take a jeweler's loupe or a good camera and zoom in on the trichomes heads.
If they are all cloudy, the plant is ready to be harvested.
If there are still some clear trichome heads, let it keep growing.
Good luck!
