Hey there so bio bizz is a good option if you're looking for a bottled nutrient system. But if you prefer single ingredients or blends that are dry and good for soil amendments, down to earth is good. They have many varieties that would be like dilligaf mentions individual dry products like rock dust, guano, langbeinite(potasssium only).
Either way you choose you'll want to find a nice "grow" nutrient for the big/taller part something with good nitrogen, bone meal/bat guano etc. And then you'd want something high in PK for flowering for the "fatter" part langbeinite/sea bird guano etc. The rock dust/greensand etc will help with the micro nutrients. Otherwise bio grow, bio bloom, and their fish mix is a good choice.
Happy growing and happy choosing.✌️
