Your Black Beauty eggplant is a WATER HOGGING HUNGRY HIPPO that likes lots of organic matter in the soil. I've grown black beauty before in eBuckets, in a mix of 1/2 MG potting mix and 1/2 Black Kow Composted Manure. Try working some finished compost or composted leaf mold or some other organic amendment in with the Beauty.
Nothing beats a wish but a try!
Here's a Black Beauty I grew, and some Beatrice Eggplants. Both grew in homemade eBuckets with built in reservoirs, so they'd stay hydrated when I couldn't get to watering them.
