Oh! These are autos right. I'd dont think you top those.Didnt top since they super small didnt want to stress them out more.
Is it too late to lst just the main cola so the others can catch up?
If these were photoperiod plants, and you pulled the top down you could stop flower. Its different if the plant grows into LST over time. Or a scrog. Pulling the top down below the lower leaves really only works when you have a leggy plant that is reaching for light. The hormones change and it veggies out, the lower stuff gets a second wind. but you wouldn't do this unless you ran out of room and it was gonna go into the light. It's a last ditch effort thing. Even then you gotta go slow.
