Looks awesome.
auto at six weeks, so i'd let it grow vertically on terminal shoots about now.. . at least by the time you see budlets start.. probably 1-2 weeks of vege-like growth left at that point, guesstimate on autoflowers is tough. Try to let it grow vertically together now... should get 12-18" shoots all over.
Looks great man, only suggestion i'd have is don't leave the plant matter you trim off or that falls off on the soil.. it's just food for pests.. Happy growing! 👊
