Clone trouble, can you diagnose this? PICS

So ive had these clones for a few weeks that have been looking great, as spring approaches the bugs have been getting more rampant along with the basement they're growing in feeling like a nasty musty basement. I have plans to get them to a different area soon but im not sure what is causing the leaves to do this. The new growth looks good and that they turn into what kind of looks like overwatering but that definitely isnt it. I did have a gnat problem a few weeks ago, could this be the larva feeding off of roots?

I doubt it's larva...
Plants lighting under picture makes girls look ill....
Soil?
Nutes?
What did you do after you brought clones home...
Those leaves, well, they look to me, as if they are NPK deficient... you feeding them yet?
Look under leaves...
Keep an eye out for white power mildew... CA friend bought clones from Store in OC, and introduced WPM to his whole property...
Buyer Beware...
Good Luck man...

Thanks for the reply! they look worse in person than in those pictures, a few seem like they could be dying but im in ocean forest right now, they were transplanted into 3 gallon pots and i gave 2 of them light nutes but i dont see a real big difference in the ones that got nutes and the ones than didnt. what would you recommend feeding them?

Hard to tell with the pics, lighting...but just a thought...looks like wind damage? Not much info. on the grow room, but you said the basement felt nasty musty, if your using fans...? Just a thought... looking at the leaf shape and Flatness of it, Take a look at your air flow!
