Main lining early

I see you’ve already FIMd. Recommend you don’t pile on with every technique they list here on the site. Just let her grow. And next time, ideally, let her show you her true expression. I.e., no topping, fim, training, lollipopping, mainlining, etc. Yes...you have a small space. Find a baseline for any genetics, then determine what stress techniques, if any, are beneficial and lead to an increased yield beyond it’s baseline. Make records take notes. Sometimes, less is more, or nothing at all is best. It can be tricky with unknown genetics because you can’t afford to end up with a lanky sativa in that 5’ tent, but I don’t see how that thing is going to outgrow your space if you are to flip to flower immediately and see what results. Good luck
