Q.What Happened To My Eggplant?
My first few eggplants were perfect and delicious. A month later they came out brown, cracked and deformed. Each photo is split with healthy version on left and problem on right. I noticed some meandering trails on the leaves, but other than that nothing. The plant is still alive. Whatever has caused this is not killing it.

From here, you will need a fungicide. This article will help:
