3 days after Transplant leaf coating issues

Fox Farms Coco Loco and Kindsoil
Transplanted from Propagator 77 degrees 65% RH
Plain Water - dechlorinated 6.9 PH
Black Dog LED 400 22 inches from canopy
Solo cup to 5 gallon Cloth
Current environment is 75-79 degrees 60% RH

On some of the lower leaves a few days after transplanting I ended up with some of this.

Is this perhaps from shock or light difference? I used the same light for them as seedlings and they did fantastic, just removed the lid now and lowered the light slightly.

I haven't noticed any yellowing, to me it looks like the outer coating is gone.

Anyone?

I believe my concerns were due to windburn. I moved the fans a little and it doesn't seem to be re-appearing.
