Deep ribbed, paper"ish" veins after moving to HID? Please help (details and pics!)

Thanks for the help!

What changed from the plants that were doing great to these deeply veinated ladies? I moved these plants from fluoros (96W) to under my 400W HID. They then began to exhibit stress immediately. They now have deep ribbed and paper"ish" veins. Primarily in the new growth. Could this be light shock? Maybe temp shock (since the temps went up for a few hours...but that was 6 days ago). Too much Mg or Ca? Under/Over watering? This has been going on for six days and I cannot find anything with my search results. Please help.

BTW, I put them in my ebb & flow tray just for support. They are being top fed by me, not the flow. DI H2O with CalMag added. PH of 6.7

Soil: Fox Farm Ocean Forest
pH: 6.7 in, 6.2 runoff
Lights: 400W SuperHPS Hortilux (15" above the the tallest plant)
Temps: 73-76 (Portable AC)
Good ventilation

Are they rootbound?
 
No, I had just transplanted them to these larger white pots a few weeks ago and they were stable before I moved them under the HID. Is the light too close? I have the AC keeping the temps under control, so this should not be a problem. The ribbed leaves started on the tallest plants and worked its way to the smaller plants. Newer growth only. The lower fan leaves look normal. Hmmm...
