Are Brown Leaf Spots Permanent?

I caused Leaf Spot disease on my indoor Corn Plant by over-watering. Once a week for at least 4 weeks I’ve been spraying with Fungicide 3, and have reduced watering. I think I’ve stopped the spread of the Fungus but a) are the brown spots left behind like a permanent scarring or can they go away and b) how long do I have to continue to spray this plant?

You can remove the leaves with brown spots if there aren't too many. If a lot of them have spots, wait till you get several new ones, then remove one or two of the old ones with spots. The spots won't go away. In fact, removing the leaves will also help get rid of the fungus.

You can stop spraying, it sounds like you are on the right track with the watering. Fungicides really don't help much after the fact, they are better used as a preventative.
