young plants wilting after transplant !

They are drying out for some reason. I would be pumping nutrients to them 24 hours a day if you arent already

A few of those look like it is more than just transplant shock. ensure the driplines aren't clogged or unenly distributing water and that enough liquid is dripping over the roots.... maybe, those roots haven't grown into the reservoir at bottom yet? something to do with water uptake is most likely different between the pots. Those things look like they have no water, which would be odd in a drip-dwc. The one's apical meristem can't even hold itself up. A few of those plants have lost "turgidity" or "hydrostatic pressure." in a dwc you can easily eliminate possibilities by checking pH and calculating your ppm per molecule used from your guaranteed analysis labels. google "manic botanix ppm calculator" .. should get you to a decent one that can handle specific gravity, if needed.
