Hey all,

From my understanding any plant that produces some kind of fruit (like a tomato or strawberry) usually requires higher amounts of phosphorus when planted in soil during their flowering/fruiting phase of life. I'm just curious how do these kinds of plants get their phosphorus requirements met in Aquaponics? Am I correct in understanding the primary nutrient in the AP environment is nitrogen in the form of a water soluble nitrate? If so, how do Tomatoes and other fruiting plants do so damn well in AP?

Someone told me that if I ever have problems with fruiting plants not producing fruit it's probably due to lack of phosphorus and one person even suggested using Neon Guppies or Tetras but didn't elaborate on exactly why.

Your thoughts?
