I’m thinking about pruning down under to redirect all nutrients up. It’s a stubborn original glue auto ! Not sure what to do 60 days . Talking about the tall ones .
You gotta be careful using training on autos, LST works great, topping and everything else can also work fine but one has to remember its an auto and the time it has in veg for recovery, you do not want to do anything to her too late and having her try to recover in flower
How much light ya got in there? I strip the bottom 1/3 approx. of each plant to help with airflow and redirect energy - works for me on my autos but I don’t grow monsters - lol as long as you have enuff light/penetration- be patient looks like they are just getting started .
more info on the grow would help - medium, lights, space, even natural light pics helps , nutes used etc
