Humidity problem

I'm 2 weeks into flowering on my stardawg auto, cause of where I live and the weather it's impossible to get the humidity below 60% sometimes 50% on a good day, I've got dehumidifiers and good ventilated air but still can't get it any lower, temperature stays around 23°, I want to know what my chances are of my plants getting any mould as I really don't want that to happen

If you have adequate air flow you should be ok. I run 60% from start to finish no problem.
