I approach Botrytis with a H2o2 Spray / Mist to dampen the infected area, then carefully spread the flower and continue spraying to keep any spores from dusting anything else around.
Once the flower is disinfected / dampened, I locate the Node and remove it from the stem.
If the stem is slightly infected, I'll spray and do a slight wipe and cleanup of the stem, I'll later keep an eye out while Scouting as the days continue and spray the stem if necessary.
I've had a good success with this surgical method.

Thank you ! It's one of those things, that I literally didn't know what it was... My brain went from "Maybe the PH is bad....nutrient deficiency because it only affected the leaves" to basically wondering what else it could be. The first time, I had no idea what it was, and same for the second time, and it only affected a few plants, so I'd be confused what was happening for a bit. I watched carefully, and when the infected leaf began to rot (some of my plants, there simply isn't a way for me to even see the tops, so I didn't know how bad they'd be) it rotted into the bud, causing actual bud rot, and on some extreme spots, it'd even nail the stem too, and that's where I lose whole tops If I open it up and see white on the stem, I cut the whole thing and toss it.
This past season I had a few more plants that got it, and on one, it spready so quick I lost most of the plant, only got maybe a quarter or half a pound off it, because the first ten tops I grabbed, were all I managed to harvest from her. This season, when I started seeing it again, I got nervous, knowing full well it could, and would, spread everywhere. Not all plants got it, but the humidity spiked up early this season, and stayed that way for a while. I did lose a lot of some of the plants, but at least knowing what it was for once, I now know I need to rework / plan out where every plant goes, so that I can increase natural air flow, and try and avoid it from returning again. What is left in my garden isn't a whole lot, but still enough that we've got work to do.
Appreciate you taking the time bro
