Gouldian molting but bald patch not improoving?

[Howldaloom]

Hi my male red headed purple breasted male in the last year has lost some feathers around his eye. Skin is pink underneath and he has been treated for air sack mights, scaly face and mites.

He is currently finnishing a molt but the bald patch is still there.

All through the molt i have provided iodine in his water and feather fast on his food. My hen also has a bald patch from matings that hasnot grown back. pink skin underneath.

Any thing i should worry about?
