Yeah don't believe any of the myths you here about autos mate. I busted them all with my profile pic. Topped, supercropped, tied down, tied up, transplanted , defolled the shit out of all the way through the grow. Even shouted at her a few times lol.
They are pretty fragile the first 2 weeks and will stunt if you mess with em too much but so will a photo. Just that with autos you don't get the recovery time so gotta be careful till the roots are down.
Lots of people tell you not to chop em up but those are generally people that can't get them to grow like you can. Long as they're going full tilt and no issues they're pretty indestructible.
You've obviously got this fairly dialed in so not something you should ever get dramas from.
Watch your environment though bud. They're getting a bit stressed from iether temps, humidity or a light being too close.
Your buds might go foxtail if you don't get that under control over the next few weeks.
