It looks like defficiency of nutrients too me. Pic2 obviously has some problems with the nutrients balance because of the leafs not being able to support them self. Im thinking it could almost be lack of zinc, but with lack of zinc your leafs start to rott. Hmmm I would suggest doing what Zandor told you to do. Get a TDP to determine your nutrient levels and the heat coming off your light. It could just be a hydration problem. Pic1 = Lack of zinc. Its rotting the leafs at the end. :O. I dont know if you'll be able to save those they're so small, you might not have enough time unless someone on here or you go out and get your TDP and the supplys you need today..
