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.

This is a fungal/bacterial infection. It can be caused by insects, but is more often caused by wet roots that don't have a chance to dry out between waterings. Eggplant need lots of water, but they must dry out down to about an inch or two, very thoroughly, between waterings.
From here, you will need a fungicide. This article will help:
