Neither of those products are certified organic. Since I prefer growing organic I use Fish Emulsion. If you wanted to get more Potassium and phosphorus you could add wood ash Which is what I use. Like Mrs J said kitchen scraps and compost. I am putting all my banana peels on my sweet potato rows since they love potassium as an example of how to use kitchen scraps. You can get 5 gallons of fish emulsion in the fall for 95 dollars and you get a nice bucket.
