I don't use any guano, only poo I add is worm castings. I add a few more amendments to the organic mix I use that contains: Hydrolyzed Feather Meal, Pasteurized Poultry Manure, Bone Meal, Alfalfa Meal, Greensand, Humates, Sulfate of Potash, and Sulfate of Potash Magnesia.
Once my soil (soilless medium to be more precise, peat moss, pro mix.) is all mixed and cooked, I don't ever "feed" my girls. Only aerated tap water. Nothing else. I don't even PH or test anything. Spoiled with good water. The initial amendments will give vigorous growth for around the first 30 - 45 days. Then it's just top dressing every 30 days til harvest. Generally once at flip and then again as she's finishing her stretch. And the reason I started this response, the mulch. We mulch for a few reasons. Moisture retention, we automatically add organic matter, we protect the top layer of the soil from the air and light, thereby allowing feeder roots to access the reservoir of food our topdressing has provided. By offering protection to the soil we also protect our microbial herd. If you allow your herd to thrive your plant will also. I've been working on a budget grow thread, I'll be sure to put a link to it in my signature so you can read through if you'd care to.
