I have tried aquaponics pretty hard about two years ago. I found the idea super interesting ( and still do). After a while my plants started decaying over time. Getting black spots, very white. Started having holes in them, ... After further reading, I learnt that plants need more than just nitrates. They also need manganese, calcium ... A whole bunch of elements you can't get in a closed system (nor in the fish food directly). I went back to growing outside. I would definitely recommend aquaponics, but for people that can setup their system outdoors where rain water will bring all those needed additional elements.
