Is she ready

Unknown strain at 42 days flowering most hairs have turned and most of the trichs are milky I think I'll be lucky to get an oz from this plant

I would let that go for at least another 3 weeks, possibly up to 5. They really fatten up in those last few weeks you won't regret it. but just in case I'm wrong always remember to check the Trichs with a microscope to see if the plant is ready. There are a ton of threads explaining that on this site

Good luck!
