HELP Seedling leaves curling under starting to twist??

Ok so my seedling is one day shy of a week old and the leaves are curling under and starting to twist (just like the title says). And also, the new leaves that are coming in are almost yellow, and it looks like the tips of the leaves are starting to turn brownish, you can't really tell in the pictures.

I'm using rockwool and I soaked it in PH'd tap water for 24 hours before using. I put the starter cube in the 4 inch cube on 3/2 and haven't watered since. It's just starting to get dry today and will probably water tonight.

What do you think this could be? Could it possibly be a ph problem? That's what i'm leaning towards...if it is, what's the best way to fix it?

BTW i haven't used any nutes. I plan on putting it in a DWC system tomorrow with fresh water. The strain is Snow White and is known to be somewhat of a light feeder. But if this is a deficiency I'll probably use like 1/4 or 1/8 nutes when I put it in the DWC.

The problem might not look too bad but it's definately not normal, I have a plant in soil right next to it and it's doing way better. I just want to get to the problem as fast as I can, I really don't wanna lose this baby.

Help is really really REALLY appreciated!
Thanks a bunch.

i may not be correct in saying this, but i think it may just be the genetics of the plant. right now i have a few babies from seeds outside. one of them, a bubba cross is looking very similar to that. the first set of leaves are all crooked and retarded. however the next sets produced are looking a bit more normal.
if i can get off my ass and get a camera i'll show you pics of mine to compare

yeah if its the earlier leaves dying thats normal. yeah i would water it right away!! and maybe give it a bit of something like superthrive

yet another uncompleted thread...
there is so much great yet poorly organized info on this site FML
