Prune lst or leave it be.

probably more about your substrate and how you water/feed -- if you want to try either, or both, go ahead. Plant is healthy enough it looks from picture. if you bend it over, remove leaves that smash against ground. May need 1 or 2 off the new 'top'. But, if you bend it down between the 90-degree alternating nodal growth, you can allow everything a clear path vertically and immediately. Shouldn't have too many leaves in the way. Be gentle when forming a bend. weaken it a bit in a few places and you can get her mostly horizontal. tie down top, possibly something to hold middle down, so you don't get a big arch with ~2 auxiliary buds stealing most resources at highest point. or, prune the top node or 1.5 nodes, posssibly remove 1-2 leaves up top if 2+ axuliary buds are burried. It's good that your plant has some auxiliary growth. I think topping works better when it's out a node or 2. Seems easier to get them even with minor shaping/bending while others catch up. I prune when i LST too, but for different reasons. It's secondary as the bushing will naturally occur. I'll prune where growth is too fast, or where i want a need some extra density of colas later on, etc.. if oyu just top and keep topping, you;ll get similar results and likely can keep it a bit more even up top = more even colas.
