Seedling Nute burn?

I just noticed tonight some brown spots on my only two fan leaves.

I am using MG seedling starter which i know has nutes in it. I am afraid to transplant it cause the roots are probably really fragile.

What do you all suggest I do?

Thanks for your help.

I was thinking about this. Does the MG seedling starter have enough nutes in it to burn a seedling?

I also had my 2 26W CFLs close and the temp was about 90 deg F. So it might be from that.

You think I caught it early enought to have it pull through?

i think it was the high temp not nutes. if the newest growth at the very tip is not damaged it will probably make it. it'll just rely on the next set of leaves.

yep from the heat.just watch for nute burn
