Hello amico, I think you stressed too much your plant with transplant and topping, let her rest for now and the grow will surely speed up, at the moment I think you are at the middle between slow and average.
I'm tryin mainlining too (Nebula version) so you can write to me for everything, I hope I could be an help.
Apart from this your plant seems good, maybe red branches are a deficiency sign, good luck with your grow 💪🏻😎
