What nutes are they getting? Looks like they need a trace min supp. Not N. Sulfates yes. How's your pH? What's your water like? -granger
 
I'm no expert, but it looks like some cal/mg wouldn't hurt. They also look hot...maybe light too close or temps a bit high. if they were mine I would mix some quarter strength base nutes with quarter strenght ca/mg supp. and some vitamine b1 or superthrive and spray them with the lights up high tell they dry. I bet they green right up!

Thats one of two things IMO. Its either a cal/mag deficentcy or lockout from overwatering. Im leaning towards cal/mag issue.

Deff looks to be low PH. Check your runoff. my babies looked exactly like that last week. Ran 6.5 through it until the ph went up ot about 5.7-.9 from 5.0, and they bounced back two days later. Happened to me because I let it dry out for one day in coco, and I'm assuming salt built up in the medium.

I think that everyone has touched on what it could be. It sounds overwhelming, but it gets a lot simpler when you realize that it is possibly all related.

You definitely have both calcium and magnesium problems - the light edges around the leaves are indicative of low Mg, and the necrotic spotting (the dead brown spots) are usually from low Ca. If the combination of your water and nutrients have adequate levels of both, then low pH can lock out the plant's ability to use what is there. If the pH is ok (the desirable pH levels are different for hydro vs soil), then you probably need a CaMg supplement.

The leaves curling up at the edges are indicative of too much heat and/or the light being too close.
