My first cannabis growth with sour ripper

Hey everyone, I have a sour ripper plant in my 40x40 cm grow tent, and I've shared my light setup above. I need your opinions on whether I should transition her into the flowering stage or wait a bit longer. I think I may have trimmed the main stem too much to the side, and I'm a bit worried about it, honestly. This is my first grow, and I've made some mistakes along the way. Should I perform more low-stress training (LST) to the opposite side of where I trimmed the main stem? I've also removed four big leaves from the bottom that were covering a significant amount of light to the lower branches, and I've just performed four toppings. I need your opinions , happy growing all!
