Normally, my soil consists of roughly 50% mushroom compost (or another quality nutrient-rich compost), 30% perlite, 10% black peat, and 10% of other additives (like blood/bone meal, earthworm castings, etc.)

I don't need to fertilize much because of the organic goodies in the soil, but I do make organic "teas" when I need to fertilize. I like to take about 1-2 ounces of guano and stick it inside a net stocking, then I let the stocking soak in a five gallon bucket filled half-way with very hot water. After about an hour, I'll fill the rest of the bucket up with cold water and fill milk jugs with the contents. Bear in mind, this is to water sometimes ten or more 5-gallon buckets...so you may not to need make quite as much.

Bat guano is one of my favorite flowering fertilizers, and I've used everything from Nitrogen-rich guanos to fish emulsion for veg. In about a month or so, I'll be giving an organic fertilizer called Rainbow Mix Bloom a shot. It'll be my first time working with Mychorizae fungi, too...so I'm hoping for the best!
