It’s so hard, I mean the flower time says 8 to 10 weeks and I’m currently at 8 weeks and 5 days. What should I do?
You should sit back and enjoy the grow. You've got some pretty impressive plants but are no where near harvest since your pictures show lots of white pistils. I don't even start looking at the trichomes until the pistils turn dark and curl in. Then you are getting close and clear trichomes turn milky and then amber.
The high is most energetic and uplifting at the milky stage, and more body stone/couch lock at amber as some of the THCa turns to CBN. So, depending on what effect you like, you chop at the appropriate mix of trichome colors.
So, put the scope away. Show us your hands and back away slowly....
