Help….found tiny bit of white mold…

Hello, so I have 3 plants, all diff strains growing in their 10th week of flower….one plant is real close and could be harvested IMO.
I was giving them the once over while watering this morn and found a couple very small spots that look like white powdery mold…..also, it looks like a few of the places where I snipped leaves, much earlier in the grow, look like they may have it…..they appear chalky white.
What should I do w/it being so late in the grow?
Plant 1 is the closest, has a ton of amber trichs on its calyces but still has just a handful of white pistils, so I was gonna give it another week.
Plants 2 and 3 are not there yet and will need 2 weeks for sure. I have not found any mold on them but also haven’t looked that hard.
The pics show the chalky areas but the other spots are so small I just can’t get a decent pic….so pics wouldn’t help. I’m confident that it’s some kind of mold and that it can wreck this grow if I don’t get it handled.
As long as it doesn’t lead to bud rot can I just wash the buds after chopping??
I don’t get it….my RH is at 40%and sometimes lower. There is a ton of airflow in the grow space.
can someone help me out here?
thank you all so much for chiming in.

How do the leaves and inside of the buds look?

They all look pretty good. I’m seeing a tiny bit of chalky color at the base of a couple buds. Those buds seemed to be growing together at the most dense area. I pulled them apart a little and spread them out.
i guess I need to watch them closely until harvest……then probably do the old 3-4 bucket wash.
Like I said I have a ton of airflow….one stationary fan blowing right over the tip of the canopy, another that oscillates and hits the plants more squarely, and another fan on the floor blowing through the bottoms. So mold was the last thing I was expecting.

Even with low RH and tons of air flow PM/BR and molds are still and issue. What I have found that works best for me is keeping my day and night temps within 5 degrees from one another. I even had to add an inkbird with a small heater to keep my night temps up and haven’t had an issue with any PM or BR since and and the spores are floating around everywhere. It was well worth the small investment for the inkbird and heater.
