seedling help

my 1 1/2 week old seedling is dro0ping down. i know the soil isnt too dry/too wet as i havent watered yet and the soil came moist but not wet wet when i got it. it was growing well but the growing leafs seemed to just like flop today. :S i had a fan blowing in the room and it was blowing on the seedling somewhat, would that have caused this or is this something else?

they are under a T12 2-40watt 7000k light about 2" away from the top of seedling

same problem here, hey try putting them in a humidity chamber, i just proped up plastic wrap on a stick, they sprang right back up, o and 2" means 2 inches, best of luck man
