Wrinkly leaves?

I took a picture of them all. Let me know what you think? They are not so much twisted(maybe one or two are) as they look wrinkly and dark. I started them in Fox Farm Ocean Forest with MG perlite. No nutes outside of whats in the soil. Wondering if its a PH problem or could it possibly be they are really sensitive and its nute burn? Bought a ph kit and it should be here tomorrow so I can test it then. Any other ideas? The plants are auto-assasin with a DNA Connie Chung and DNA Sour Cream mixed in. They are about 1 week old from when they sprouted through the soil.

So the veins in the plants are becoming more and more contrasted to the leaves and little spots are showing up on the plants. Not sure what to do because the only thing that could give nute burn is the soil.
