m0useanswered grow question a month ago That's a lot for the plant. I would lower that lights dim to around 20-40% and let it recover. Don't water it a lot. The transplant cutting roots at end of flower late in season and chopping all its branches off is extreme stress.
If its going to work, it will reveg out of the old bud sites.
I would also take clones from it and start new plants vs using the big one. Its going to grow all weird. When revegging the new growth out of he buds gets a little wacky and not easy to maintain.
It a lot of work. If its worth it. do it. if not just let it die.
