To chop or to wait?

Hey folks, 1st real time growing in 4x3 under stairs build out. FFOF soil and nutes, 3 gal fabric pots, 4 plants 2 each of Barney’s critical kush and Grimm Durban nights strains. Day 64 flower using a loupe I see a lot of amber trichs on the colas of these plants, but it also seems like they could go a bit longer. Each pic is a main cola of a plant. Thoughts on chopping?

Not ready.
Wait for the weight.

Hell yes nice grow newbie! I am so old school and experienced now I don't check ph nuthin anymore. You seen it grow so you know its happyness or not. my suggestion is let the plant go longer if it doesn't look tired. When they look tired like a tomato rip ready to pull its time to chop. I stopped checkin ph and loop trick color many years ago. just grow a garden full of awesome bud now and have other hobbies that need my time beside constant garden tender...
