Should I throw a net on her to limit her height or...

Keep doing lst and leaf tucking then add a net after you flip her to bloom if you add it now it may wind up being too low. Hope this helps👍

Continue LST and leaf tucking , even if you aff a net in a week or 2 the plants will already be in a good way.

Doing a scrog is really personal preference or depends on what you are growing in. For example if you are using cloth/airpots it is really easy to use the pot as an anchor to tie the branches down. That's what I have done every grow I've done so far. However, if you are using plastic pots, 5-gallon buckets(like in dwc), etc. with no really good areas to anchor the ties to, then a scrog is really handy. The other thing to consider is if you need to move the plant at all. With a scrog the plant cannot be moved. That's generally fine if you don't need to take the plant out of the tent at all. I will be using a scrog for my current grow as I have set up an auto watering system using universal floraflex caps and no longer have a good way to tie my plants down and won't have a need to move them anymore as I don't have to lift them to drain their saucers with the flood tray I got. So, in the end, it is really up to what you think is best.

Yes throw a net on her. Gently spread canopy even. Give 3 days to recover. Flip to flowering and continue to tuck branches underneath net at least two weeks into flower. You will end up with a nice even canopy net full of buds.
