My game plan is to give 'em a couple tablespoons of TomatoTone every 3 weeks. Then, in between the TomatoTone feedings, a light feeding of Neptune's Fish/Seaweed. So they will be getting something roughly every 10 days. With each 10-day feeding will come a moderate watering.
I do think Tomato Tone gives peppers everything they need. Last year I used it and only it, with my container plants. They grew big and strong and gave me many more pods than I could eat. I prefer not to have all my eggs in one basket, so this year I'm branching out with the Neptune's, but I still think the Tone could easily get the job done without an assist.
btw, that Neptune's stuff ROCKS with other kinds of plants. I mean, really ROCKS on herbs, pumpkins, cucumbers, tomatoes, etc. You can see the difference within a day of applying it.
