So I’m starting to trim some flower and came across this. I don’t think it’s bud rot to me. At least not what I had to cut off some of the plants this year. Maybe over ripening? As alway thanks.

1st pic I was thinking spider mites as you can just see a few fine webs, but on the bud??, but those webs look like mould in the next pic or two and those buds definitely look like they have succumbed to a nasty bud rot attack. You can see it clear as day in most of the top buds in the pics....even the main stalk is white with mould.
You could use an extraction process that will kill the spores yet extract the goodies if your keen.Flower Room: 11' x 7' x 7.5'H, 480w AC, 13gal/day dehumidifier, 1.5gal ultrasonic humidifier, 60gal (27gal usable) nute tank, 16" pedestal fan & 18" wall fan. Lighting and climate automated. Hand watering.
Veg Cupboards: Two 4x2x6H cupboards. SF2000 Evo in one SF7000 in other. Climate controlled and automated. Hand watering
Aeroponics Low Pressure Bucket: 20W LED. 5 clones & 20W LED 11 clones
Lights: Mars Hydro FC-E1200W, SF-7000, SF-2000 evo in flower room.
Medium: Coco/perlite, 7.2gal pots, no drains

What I have read is nothing kills the spores and cannot be extracted away, not even burning kills them. Sorry it sucks to loose nice bud.

Botrytis loves damp cool places. It thrives at about 18 to 23⁰C with high humidity. Above 32⁰C it can't really grow (think high CO² supplimented grows) and above 50⁰C the spores are killed very quickly, in seconds.
Fungicides kill it, soap kills it, ethanol 30% kills it all in 30s, UVC can kill it.
On surfaces in a typical grow room it has no problem surviving for 2 or 3 days but needs high humidity to germinate. In soil spores can remain viable for years.
