In need of 12/12?

Expect 2-3x growth and make sure to flip before you can't fit another ~4 weeks or more of solid vege growth after flip. have you filled roughly 1/2 the area? 70% of length and width is 49%

If it were mine , I would top down the 3-5 pairs and attempt to spread her out for a week. Then flip. I dunno from the pics she looks kind of lanky. As your first one it's hard to slow down and dissipate the pressure to get to the finish. Take your time in veg shape you future. Learning is fun. On a side note, if you only get it 80% right, you'll still have something to show at the end. Every leaf is not sacred.
