Funky foot odor

The flower or you tent in general? If it's the terps, that's nothing to worry about and no need to treat. If it's the tent in general, you need a spring clean. Stagnant water can get smelly really fast. When I've had bud rot in the past it never really smelled like anything, so don't think you have fungal issues. Can't see anything from the photos that would create a smell. Some flower is just stinky.
