Looks like it could be your light could be too low as Weed Pharma said, I would raise it up high, maybe 48" or so if you can. LED[s are powerful and will burn a young plant like yours. Could be caused by something else also but the more experienced growers need more information, "what Campesino said" Take a look at the bottom of my posts and you will see a list of things that would be needed for an accurate diagnosis.
I would go back to your other post with the info and Campensino and Weed Pharma will walk you thru what needs to be done "fixed". That's how Camp did it with me when I had the same problem a few months ago. The folks on this site are great at helping each other with problems. Hope it gets figured out before more damage to your plant.
Photos taken with the LED on don't show true colors and such, I turn mine off and use a flash for best pictures.
