The plamt is looking great and bushy. And when colas begin to get big, you may need some sticks of bamboo to help hold them up but yes also to kind of separate them for good airflow. I think your light will also be good through flowering, 1200 led is pretty powerful. However if you were to do a slight defoliation and remove any leaves blocking those bud sites, it will help immensely, taking off 10-20% in the veg and then another small one into early flowering. Just dont get too carried away removing leaves as the plant will still need some good healthy ones. Happy growing great job already.

Think of defoliation as a last resort. First try to LST to open up the canopy and/or tuck leaves. Now when defoliating, what you want to expose is not buds (or stems), is lower leaves that are connected to those lower buds. When selecting what leaves to defoliate, be sure there are other leaves below to catch the light it was receiving and that on the point where it join a branch / stem there's smaller leaves that will continue to catch light to feed said node. If you've never done it, do a couple of leaves each time, or you might get carried away and leave a bald plant.

My recommendation would be to let her grow. Obviously, get the temperature back to where it should be too. But she should be fine. Cannabis is much more resilient than most people give it credit for. Good luck! 👍
