Seedling Defiency ?

PowerK said:

I have 4 Moby Dick seedlings about 1 week old. Growth is doing fine, but I have them under a 300 watt led light hung about 6 inches above them. It is cool on my hand so heat is not the issue, they are also getting enough water. I usually start them in a regular potting soil but this time I put them in a soil with no nutrients added. So what can be making my seedlings like this? I heard seedlings don't need any nutrients (could it be a micro deficiency?).

Problems:
-Leaves feel dry to the touch (no moisture in them)
-Cotyledon's are a purple tint
-Edges of leaves look almost black like they are dying
-Leaves curling upwards

Any help would be appreciated, thanks.
