They Look great!
I meant top and then gently train the (now) side shoots that will (then) be the new main stems (after you top the plants). So you top to above the 2nd 3rd or 4th node, then once the side shoots have grown out (which they will, you sill see!) gently draw them out to open up the middle of the plant to the lights.
Some folks pull them down fully flat, others just draw them gently out to a more diagonal angle. Experiment a bit and see what you like!
This will help you get more budsites lower down in the tent. Once you have a good number of them (the new branches and budsites) at a fairly even height with each other, and you think the root system is ready, up-can and flip the lights and try to keep the tops even as they stretch. (You can upcan before flipping the lights - that's just how I do it, mostly. I’m still trying out new things myself
)
WHen topping, if you can, try to leave some length of centre stem below the cut. This helps to strengthen it and guard against splitting.
