newly planted clone Just plain droopy.

Just transplanted this damn thing into the DWC. have roots in the water. using AN sensi 2 part. wtf? no temp issues, lighting is more than adequate. I just did a rez change just in case.

I had the same issue, and after a slight panic attack my research, and very trusted master grower told me that sometimes they go into a sort of transplant shock for a few days.(in my instance it lasted exactly 3 days) He pointed out a variety of reasons for the shock, temp changes, difference in light intensity (that was my main issue, went from T5's to some intense HPS). I used a product called revive as a foliar spray and overnight they rebounded. Hope some of this eases your worries.

P.S. I was also DWC and my roots were growing nicely during the droop phase.

Give it some time. If you damaged any roots they go into shock. It's a weighting game. Much like the first 3 days of cloning. Realy not much you can do but see if they spring up.

if you have gone from a propagator/dome of some kind (very high humidity) straight to the grow environment (lower humidity)
some of the clones can wilt very quickly, within an hour

the ones that wilt need time to acclimatize to the new low humidity levels
when i first take my clones from the propagator and place them on the lower humidity main system, i put a large plastic cover over them to raise the humidity
for the first day or 2 with the vents open,
i do it more as a precautionary thing as most cuttings are fine on the main system as soon as they come out of the propagator
