I'd pull him back off the kibble.
An over the counter med you might try would be Pepcid or Tagamet or Zantac.
Be sure to tell the vet when you see them if you use any of these.

If that helps then you can see if some bland food and plain pedialyte added to the water bowl will help.
I would suggest trying boiled chicken meat or hamburger with the fat drained off, mixed with really well cooked rice in a ratio of 1/3 meat to 2/3 rice to see if that works. It's not a balanced diet but OK to use for a few meals while working on controlling digestive upset.
I'd suggest having your vet check him for intestinal parasites such as giardia or coccidia. I've had good luck treating non specific diarrhea with metronidazole (Flagyl) an antibiotic drug used against anaerobic bacteria including coccidia and giardia.
Check the food label on the Flint river food. It may be your dog is not doing well with wheat or another ingredient.
You could see if a food such as California Natural Chicken and rice will work as it has very few ingredients and matches what the dog does OK with on the home cooked diet.
Hope this helps you!
