Couple of things...

1) Might want to refrain from photographing your fingerprints, for obvious reasons.
2) What are your temps?
3) What is the ph of your water, and the run-off?
4) Have ya got enough perlite in there, lol? (looks like a bit too much)
5) Do ya know how to adjust your color balance on the camera? With the hps light, it turns everything yellow and makes it impossible to tell whether or not there is a problem.
Perhaps it's the recent transplant, or just the camera, but droopy leaves and yellowing is not something you want to let go on for any length of time.
