Photoperiod What could this be???

[Mikescottson]

This is a photo I'm growing under a marshydro300 3 gfp HF medium 2 weeks into flower.
On one of the bud sites the pistols turned this brown.
Does someone know what this could be??
These photos were taken last nite,no other sites have this happening and my other plant doesnt either.
It's only this one top.

Usually the pistols start turning colour once they mature, to me it looks like the natural aging process. Anyone else?

Definitely not natural at week 2 of flower.. You need to check for "bananas" or pollen sacs on that plant and on any other pant in the same space. Looks like it hermed and pollinated itself, or another plant in your garden hermed and this bud was pollinated. I bet a $1 that that's what happened. You'll probably find a few more bud sites like that, but let's hope not!

Hmmm all the above check = light height check
