yay or nay for 6 weeks?

The majority of these have been in veg for about 6 weeks with tomorrow marking the 7th. I feel like I may have been neglecting optimal timing with transplanting can I get general opinions and observations? http://youtu.be/lOu019Xz5uo

Hey man.. I was really trying to start, but I was flying sideways so much I got dizzy =\

They look like they stretched, but nothing a deep transplant couldn't help if you choose. Otherwise I really dig your node spacing up above. FWIW I have a Northern Light in an ebb & Flow tray thats about 6-7 weeks in and isn't anywhere near this big =)
