Human waste
cannot be used for food production to the best of my knowledge, and I know factually that the use of animal wastes *and* compost are very strictly monitored, controlled and regulated by NOP (National Organic Program) standards, and subsequently all other certifying bodies' standards. When we refer to human waste, we're usually referring to solid material, aka feces, aka humanure.
Therefore, certain precautions must be taken when using urine, specifically (I'm not discussing any other waste, such as night soil here).
First, NO SPLASHING. You don't want it on leaves at all, let alone leaves, flowers, fruit or florets of any produce that is consumed raw.
Second, source. If you have a UTI, are on medication, or have any other infection issues, you probably should not use your urine. This is the only real possible source of the contamination mentioned above. Otherwise, urine is sterile when it exits the urethra and only picks up microbes when it touches external skin and the like.
Here are a couple of practical articles on utilization of human urine for fertilization. The vast, vast majority are using collected, and therefore ammonious (is that a word? You know, when it starts to stink) urine.

Vegans are getting into it:

It is sustainable for more reasons one might initially realize:

And, it works.

Obviously though, one size does not fit all. How it's handled and the social stigma are the only hurdles I see, however. :)
So far my small indoor grow (6 plants) is coming along nicely using only diluted urine for fertilizer (plus a little vinegar to get the pH down to the mid 6's.)
The plants are 5-6 weeks old, healthy, with no leaf discolorations except for a few tippy tips of yellow. As long as all looks well, I'll stick to this regimen for vegging.
Haven't yet decided what to do for flowering in terms of soil & nutes. The current 3 Qt containers have home grown compost which I felt had to be sterilized first. Not gonna do this for the final transplant into 5 gallon containers so I'm going to break down and buy specialty soil.
Would like to continue using urine as the primary fertilizer. Any suggestions on what I should supplement it with during the flowering stage?
Tanks!
I, thus far, have been unable to produce enough urine to make that my primary feed. I would alternate feedings with something like Fox Farms Big Bloom, along with seaweed, bone and blood meal teas, and/or fermented plant teas, and one of my favorite things, Sea-90. I haven't tried Sea-Crop, I've been very happy with Sea-90 for micronutrients.
