SOIL Orange spots

[Gjourney101]

Today I noticed a small orangr spot on one leaf and some slightly orange edges. I'm using Miracle Gro soil and have had my 300 W LED at about ~10 inches from the top of the canopy. The only orange/red I found was on the top most leaves, nothing below it. I since moved the LED to ~18 inches away. Could this be light burn or something more serious? I jave also noticed my lower leaves staying flat, thick, and healthy while my top leaves look stressed (edges somewhat turn upward)

They are making a taco. It’s a good indicator that your light is too close to the plants. If you already moved it away, try and look at the plant the next couple of days. If it’s progressing, move it further away again.

How about a couple pics of the whole plant just to get an idea. And did you move the light down to 18 or up to 18? Leaf looks healthy overall. Light burn usually shows along the jagged Edge of the leaves as dry crisp. If it keeps progressing even with the light raised up you might want to check your ph. Also give the plant a good inspection for any creepy critters that might be eating causing these little discolorations.
