Plants look a little ill!!

My first grow and all was going well until a couple of days ago. They are from seed - Top 44 - which I got because it's supposed to be ideal for beginners and easy to grow. I have 4 plants in a metre square area under a 400w grolux light with white walls. I used miracle gro compost and water when the top of the soil is completely dry. I have no fans because I thought there would be ample ventilation in my shed. The temperature ranges between 55 and 75. They sprouted in about 3 days and are now about 4" tall. It's now 2 and half weeks and they looked great until about 2 days ago when i noticed the leaves beginning to curl under and one is starting to turn yellow. I have attached some pics but you can't really see the yellowing. Please help - I feel like my children are dying - or am I worrying too much?

they are far too small to be under a 400w HPS, I wouldnt put them under that until they have at least 3 or 4 pairs of leaves.

i have the light about 18" away. would it help if I highered it?
Yeah, that's way too close for a baby that young. Raise the light to about 3 feet away, then slowly (about 2" per day) lower the light.
