The brown spots look like they could be oedema, also common when over-watering enters the picture.

It's always difficult for me to tell you what to do - not because I don't know how to treat it, but because I don't know how far you want to go or how you feel about using an over-the-counter systemic fungicide with tebuconazole in it. Fungal infections are best treated prophylactically (by preventing them altogether). If it was my plant, and I really wanted to save it, I would use the systemic, wait 1 week, then cut it back hard and make another application. I would follow the second application by a third, 2 weeks after the second.

The plants are readily available at many big box stores, so it might be worth it to retire the one you have in favor of another. Remember, they tolerate dry conditions very well, so don't over-water, and they need sun and good air circulation to keep PM at bay.
