It's just one leaf, but since it's at the top, i suspect i've over-fed something. Any ideas? Could also be burning under the light, if it is, wanna fix that

Looks like it could be light burn from the heat.

Thanks, that's what I figured, i'm maxed out of my light height right now, wanted second opinions

UPDATE- It looks like I was experiencing light stress due to a PH lockout/PPM buildup. I came to this conclusion because the burning started long after the stretch stopped and then around 5 days later I noticed flowering had been stalled a few days, so today I flushed with just clean distilled water and turned the light down about 5%, gonna see how they react. If anyone knows if turning my light down as far as brightness will reduce quality, that would be useful information. Like i've said, I know growing, but this is my first time with a tent and light (:
