as far as I can see they look pretty healthy, keep in mind i'm far from a professional as this is also my first time i've just read alot

one reason they look like they've stopped could be caused by all the nitrogen they're still getting from the soil or from the nutes you were giving them.

Give it a little time and I'm sure they should start filling out..dont know how much taller they'll get but you should see drastic differences in a couple weeks on how much more bushy they are

I really hope I could help like I said I'm not a pro grower its just no one would respond so I wanted to try to get you some advice asap then the other guys can fill in the cracks :rastasmoke::rasta::smokin:imp:
