Baby plant problems

I am about 10 days in. Im using a 400 watt MH. it is about 75 degres F only 37% humidity. sense the humidity is so low i raised the lights up. So the lights about 2 feet 6 inches away from the plants. Have not been using any nutes yet. Just regular water. There is no color problems. they are all a nice green color. But the leaves of a few plants are becoming deformed.... but mostly curling up.... it is odd becuase out of the 5 i had 1 has been fine the whole time. 2 were fine till yesterday. and 2 have been having problems the whole time. I have no clue what to do.

the last two are the best ones i got. if i need to make the pics bigger tell me i will... but i can see its preety well... the third pic is the worst plant. the two big fan leaves pretty much dried out. was kinda alive. but i ended up cuting them off. so the plant would not waist its time on a dead leaf. but as your can see not discolored. just curling up...

I cant see your pics,but I use a little calmag and that seems to clear up the twisty,deformed,curly,leaf problem when I get it.

your light is too close, give the plant some time to grow up a little before you go full bore with the light

click picture please

maybe now someone could help me out sense these are the pictures of the plants that are the most screwed up. the 400 watt light is over 2 feet away from the plant... could it be the humidity that is doing this?

the light are 3 feet away from the plant now and they ave been for some time now... nothing is getting better.....any ideas?
