This bud rot?

Hey all just wondering if you guys think this could be the start of bud rot or just light burn? Iv kept the humidity fairly low and a fan blowing above the tops of the plants, i will admit this one particular bud did get within 8 or so inches of the light because this plant decided to grow taller than the rest so the light was close to try and supplement the others anyways lemme know what you think. Plants are 7 1/2 weeks into flower

Impossible to tell under that light.
Take closer pics of the buds under natural light.

Doesn’t look good, dead fan leaves equals high potential for rot/mold at the stem. Those leaves show the tell tale signs of rot. Open up the bud where the fan leaf is and look in, if you see mold or if the bud pulls apart easily then you have mold or not.

It seems bad to pull apart a bud but if you do an invasive check now you may be able to save some of it, leave it and you will lose all of it.

good luck

Just looks like a few heat damaged sugar leaves, but do a little inspection...You'll know if it's rot.
