How much room do you have to flower in? That is where your answer lies. Looks like a small tent, if it's a 2x2 I would go with 3s, if 4x4 I would go with 5s (this is if these are your only 2 plants) I would lollipop below the netting, and bend them down so that all branching is under the net.
If tour only running 2 plants, toss them in 7 gallons, super crop the tip 1/4 of each top to lower plant height. Readjust the net. Then start weaving. Keep them short, but in bigger pots should net you a big yield.
I flower in a 3x3x6 tent. If it was me and I was using your soil, I would up pot into the 7 gal, veg for 3-4 more weeks to fill up most of the net, then flip to flower.
