Temperature plays a major role in allowing botrytis to infect a plant. If your RH is 70% but temps are 80°, the chances of getting bud rot are low.
Once cannabis hits flower, a lot of growers drop their RH into the 30's and 40's to avoid bud rot. That will cut down on the chances of bud rot but RH at that level can cause a host of other issues that come from low RH.

I didn't see anything in those photos that looked like bud rot.
One of these got bud rot but I don't recall which one it was. As best I can tell, the culprit was temps being too low (mid-70's) and large, dense buds.

Note - I don't implicitly trust an AI bot. As a software engineer for >30 years, I realize that a computer will only do what its programmed to do so it's good to ask for citations.
In this case, chatGPT is reporting available on multiple sites in the agricultural world. I've used it here because it formats and summarizes the information well.
