was browsing Youtube and came across silverarm32's channel. He says he is able to get the plants to flower without additional nutrients. I personally believe this was possible due to the combination of adding of red wigglers, the addition of brim shrimp, and the overall age of the system for a more balanced P K ratio. Check out his videos.
