Yeah, I trimmed mine right about the 2 week flower mark. The pic is them at about 5.5-6 wks. They went the full 8 weeks and are being smoked now, sooo tasty

ANd so easy to trim.
I'm running a few now with no trimming to test and see what difference I get.
Always remember, that each cab/grow area is different, so even with the same strains you'll get different results. To me it's all about finding the strains that excel in your room, then you can play til the cows come home and always have nice bud.
My room runs hot...88-92 so I do very well with Northern Lights, Hashberry, and Bubblelicious. Haven't had as good of luck with Satori yet...but still trying.
Peace - OGH
