Hydro Tomatoe Cotlyedon Leaves Twisting

[esotica]

My tomato seedlings are almost two weeks old and not looking so hot. I have searched through the forums and not found anything similar so I am looking for some input.

The Cotyledon leaves (thats what they are correct?) are all taking on a different form and dont look healthy. I just recently put them under a 400w HPS light about 2 feet away along with giving them some KLN rooting solution. Leaves are yellowish and either curl around or point up/down. One of the plants also has some brown tips on the leaves. The plants dont appear to be growing anymore and not sure what to do. I am watering once a day by dipping the rockwell cube in the mixture as well as misting about twice a day.

How they doing now!? Saw your post, I grew tomatoes also(from seed) I used flouresents and Gh nutes, they did ok. Used distilled water for about a week then very mild GH nutrient mix.
