first indoor grow

growing critical mass i put a scrog net over them and flipped to flower just wondering when should i stop tucking branches under the net?

I’d shoot for an even canopy. And once done stretching let them go

A good idea is placing your screen over your plants well before flipping. As to your present situation you probably won’t get 2 full weeks of them staying pliable enough to weave. After that the branches get harder and tend to break when bent.
