Hey bro, those clones are starting to take off !!!
I give them a week before you see noticable growth.
Sorry didn't see where you said what the light situation
was for the clones.

That lime green looks like the newer gorwth.
What I would do is take a pic a couple days
down the road and do a size comparison.
Seems like you got it under control.

I've always thought that a good powder or gel
rooting hormone does a great job to get MJ
clones uderway, IMO. peace.
