It looks pretty stressed @osowhom . Is it revegged like @Zephyrs asked or maybe had some light fluctuations?
If it hasn’t then I’m going to say the pot looks a bit small. Does she dry out much? Might be water stress if so.
I don't see anything that looks like mold yet. The white stuff is either bird poop or mildew. Mildew sucks but its not a deal breaker. Rip off those white leaves and see if the white appears anywhere else on the plant. If it does, likely mildew.
