It is wayyyy too tall to keep going with, you will just waste time. I totally get it sucks but I pushed through a similar stretchy plant and seeded my entire grow. They get stressed and herm out. If you do continue then you have to bend it completely over over and immediately flip to flower. You will have to struggles everyday to tie her down. A new plamt I'd ready for flower in your setup in a month. If you Train right away you can mange it. Don't be a dummy like me man, I would start over and train like I am. Top once and spread the 2 tops to the edge of the pot then flip to flower. We would all love to help you! I just don't want you to set yourself up for disappointment when a redo is sooo much faster. The quality of the bud will be shit if you carry on. Wish you the best. Either way we will help but don't give up and don't get discouraged, this is a HUGE learning experience for you. So valuable! Think it over and make a call, well be here either way. ✌I will change my HPS after this plant, the cheapest led costs so much here.
Anyway, what about these droopy leaves ? Root damage? What should I do?
