Photo for attention from last year's lovely season.
I moved places and overwintered the cacti inside with a fan, put them outside (not getting wet) when it got warm and they're increasingly getting fungal infections. We're getting some weird cold weather and I can't spray fungicides or I'll wet them more than I'd like. What can I do?

Some more context, they had a fairly cold overwintering, fan doing what it could and none of them developed rust until I put them outside. It was warm and the eastern morning sun even burned some of them.
I am thinking that the big temperature changes created dew in the morning and they didn’t like it. But at the same time we had some very windy and sunny weather. I don’t know how to treat them because we have a cold front happening for a few weeks.
Pretty much the only long-term cure is provide better conditions, that’s what ultimately causes most disease issues. You’ll have to decide what you are lacking.
I keep fighting mealy bugs!
