Bud Rot- Taker Her Down?

Hey guys! Thanks for reading.
I have an OG Chem plant that I started inside, put outside for the season, and am finishing in my garage because the weather is terrifying me. I have another small one of a different strain as well.This is my first big plant I grew outside so I didn’t want to risk rot..

Turns out I got some. Went into the “tent” today and found what I think is rot on one of the side colas.
The “tent” is black plastic draped from the ceiling. I’m running 6X 53w 2700k bulbs, a 150w 2000k HPS, and a random blurple.

Temps are 72-75 during the day, rh is about 45-50%. I’ve got two big fans blowing around but I can’t get the humidity down as it’s raining outside.
Should I take the big one down? The small one too? I don’t want to risk a whole crop. I removed the cola and some below the infected one. It was only a tiny patch so I cut it out and am drying the rest as a tester. Bad idea?
Any help is appreciated. This is my first time dealing with this dreaded shit

does look the colour for rot. is it mushy or powdery. mine sucame to rot this year. i chopped off what i could, but it was hiding deep within the buds and i missed it.
But your buds look nicely spread out so rot should be down to a minimum.
In hindsight, i would have trimmed out what i could if and as it turned up, the buds you get from a fullt matured plant are well worth the wait and hastle of trimming it out. i say hang in there and geal with any rot should it appear.

It wasn’t super mushy.. a little? My initial thought was “oh it burned” but it’s in suck a weird spot and the stem was soft. Plus it just looks so wrong.

I have 2 tents in a different part of the house. Any precautions I should be taking?
Sorry for the shitty pics guys. I can get better ones in the morning, I have tomorrow off.
