Over the last few days this stuff has appeared on one of my monsteras I water when the soil is dry it gets loads of light and within a day of that stuff showing up it started to push out a new leaf (last pic) for the first time in months and months (idk if that is relevant but i thought it could be worth mentioning).

My guess is powdery mildew. The way it looks like it’s growing on areas that were wet really helps solidify that it is definitely some mold or fungus issue related to moisture on the leaves.
Could be chalk maybe, what water do you use?
And are you spraying the plant?
I would just clean it off. If it comes back its likely mold of some sort.
I think that it is salts left behind from the plant transpiring water in guttatation
