I’ve fed my plants urine diluted with water, but generally if your soil life is not abundant (like every packaged soil is at the beginning because it was sterilized) it will start to smell sooner rather than later. Though that’s something that a LAB application or two will fix.
I only use pee as a nitrogen boost when they specifically need N, else I just use a complete organic liquid fertilizer from a bottle tailored specifically to cannabis (B.A.C. for those in Europe that are interested, stands for Biologically Active Cocktail). Their nutes are vegan, which I don’t really care much about, but for bloom I use TrueLivingOrganics (Advanced Nutrients’ organic line) bloom feed and a few additives here n there, along with epsom salt whenever the ladies can use an extra magnesium or sulphur dose.
