Brown & yellow spots on sugar leaves

Thread starter #1
I have these yellow and brown spots on my sugar leaves. Can some tell me what it can be?

I grow in a 2 x 2 1/2 grow tent under 2 450w LEDs use Fox Farm soil and nutrients.

Fried leaf tips is nute burn and you're leds are too close causing that coloration in the leaves. Scale back you're nute regimen and bring that light up a little further away asap! And idk about yer setup but get a fan on that baby too [emoji4]

Immediately raised the lights, thanks!

Here's another picture of the damage. Can it still be saved?

also added a picture of the plant behind it. Doesn't look burnt but looks like it might have foxtails.
