If your ships are going to be making food in any form that approaches what we are used to calling food, they will need more than "occasional fertilizer". Food is matter. So where is the mass coming from on a ship in space?

They will need some sort of bulk matter input, unless they are highly closed systems recycling waste products. (Which I guess could be what you all are trying to say, but then it would make more sense to call it a closed life-support system.) Even plants here on Earth take matter in from the ground and even more so in the form of carbon dioxide to get the carbon to make sugars.
