seedlings sick :-( help please! first time grow...

Hey guys and gals, I've got 3 plants, all are 1 week old and 2 days...

soil grow, I'm gonna repot in 3 gallon pots tomorrow morning...

vegging with CFLs then switching to HPS for flower...


I did have a fungus gnat problem 3 days ago and I watered some neem oil into the soil (I got some on the leaves and it appears now that the leaves might be dying where they came in contact with the neem)

here are the pics, it did get cold in my grow room last night (57 degrees) (I was out of town, couldn't control it)

any help guys, seriously would be great, this is my first grow and I'm very excited and wanting to give these guys the best treatment I can give them...
thanks!

I'd pot them into seedling mix for 3/4 weeks...they look like they are getting nutes..very bad...they dont need any yet so it could really f--k them up....seedling mix always says that on the bag...it has no nutes and is kind of loose and sandy...good luck with that

I planted them in fox farm ocean soil...

and 25% perlite (the perlite has miracle grow in it)(but very very small amount)
