Hello, I have had a Maple Abutilon plant for about 6 months now. I keep it inside next to a brightly lit window that gets morning sun. It has been doing well with growing tall and flowering, however it has now acquired diseased-looking spots on its leaves and has become very droopy (see attached pictures). I was hoping someone could give me some advice as to what kind of disease this may be and how to cure my plant of it.

Hm... I would almost say that this is fungal. Make sure that the soil dries out slightly in between watering. Apply wettable sulfur to the soil, along with a little dolomitic lime.
