Why are my babies drooping?

Hi all,
I put these clones under my HPS light a couple of weeks ago after they rooted. For some reason they are not really happy, take a look at the pics.
They are in normal top soil with perilite, I suppose it could be a little bit too water retentive, is that what it looks like ? Early root rot ? Temps are generally 60 - 80 degrees. They are in an outdoor enclosure.

PH, PPM and all that is ok as I have plenty of experience with that, I'm not a novice just having some trouble figuring out why this batch doesn't look happy. Any help is appreciated....

Here are the pics....

looks like over/under watering.stick your finger in the soil about a inch if it feels really wet,u over waterd. if its dry, well u get it.

also ive noticed when underwatered the branchings are weak as to when they are overwatered they are still firm but droopy.I am no pro but i hope this helps
