The curling is from the scars not being able to grow with the fruit. As long as the eggplant is shiny they are still good, just cut out the scarred parts as they will be hard. You want to pick the eggplant before the seeds turn brown an mature, it would still be edible, but more bitter.
The leaves of the eggplant look a little yellow, I think it could use some fish emulsion.
Happy gardening in Hawaii. Gardens are where people grow.
