Hi there Thaoneandonly, yeah you're totally fine with tucking branches well into flower, it doesnt cause any stress , so you're good to keep doing what you're doing, you're doing well! Hope this helps ! 🚀
No you don't you only move the ones that are covering bud sites and tuck leaves out the way the only reason you would continue to train in flower would be if your running out of head room or your plant has an uneven canopy I would not suggest giving a flowering plant any sort of stress for the first 20-30 days of flower as this is in primes stress Hermie territory Personally I would of trained this plant a bit more you have got so far already you might aswell as filled the net that would of upped your yields even more though I understand it takes alot of time to train a plant and youve done a real good job at training so far :) Best of luck anyway.
