Overwatering or deficiency? What could cause my leaves to wrinkle?

the middle leaves look kinda wrinkled looking on multiple indoor plants I'm growing. What could be the cause of this? they are about 8 weeks old.

a clearer image with less artifacting would help. Personally i dont see any real cause for concern in this image. But the detail in the leaves is pretty thoroughly obstructed by digital artifacting in this image.

What's your light? how far away is it? Have you recently upped their light intensity dramatically in a single day? what are average temps in the box/tent?

I will take better photos when I get home. At the moment I'm using 2 blue/red LED lights but only set on blue mode during veg. They are both about 12 inches away from plants. Temp is normally 75-82 degrees in my grow tent.
