It's not to late. Your plant is going to stretch 2-3 times it's current length. You can weave while flowering. The ideal timing is to fill your space with branches about half way through the flowering process. You wouldn't want to weave all your plants during veg and then find out later you got a male in the mix.bit late for scrogging now since i was going to switch to 12/12 this week no?
If this is known female with strong traits, absolutely. take some cuttings.Sounds good Brimi and what i expected to happen too - would some of the lower shoots be good for clones?
