It looks to me like they're just really far along but idk for sure. I've read that trimming autos isn't beneficial so I very rarely remove any. I can't speak for KK though
Hey yeah ur right I cut all the leafs off my plant for the last 7 days before cut to allow light to the pop corn I believe it helps a bit not a great deal.. plus I do this to make harvest a bit quicker spaced over time ect.. I dont prune any auto during veg or start to middle in flowing.
