m0useanswered grow question 6 months ago I don't think you should've topped that auto,
I can see in the third pic it is already entering flower, its going to focus on blooming now vs growing out and vegging.
Normally with Autos its best to only give them LST, some of them can take some HST but its hard to tell and takes a lot of time to figure this out.
Next grow don't top em, most optiomal option IMO, The stress causes them to enter flower early and they are on a set track to when they flower so they don't always have time to recover from the process.
Good Luck!
