are you maintaining proper pH in your water?
 
I was also thinking this could be a iron deficiency too, well looks like it at least. but my pH is 5.9 ppm 915. I will add some fresh nutrients, its been 2 weeks since I changed the res. Any other ideas what kind of def it could be?
 
As Mr. Verde implied, it's not Ca deficiency. All-over drooping is usually a watering or temperature problem. Overwatering typically droops more towards the bottom of the plant, while high temps usually cause more drooping towards the top because of lamp heat.

There appears to be some necrosis on a few of the lower leaves. It's hard to say for sure from the pics but if that's true, they may need more Phosphorus.
