To Top or not to Top

I’ve only grown autos in my tent before and have heard you’re not supposed to top autos unless they’re growing a lot. I have 6 Speedrun seed autos growing in Octopots using Jacks 321 nutes. These girls are 15 days old today and growing fast. I’m asking if should top right now or just start lst in the near future?
