The biggest problem I've seen with the organic N sources is they attract critters at the point when critters will still eat your plants. The fish emulsions attract raccoons, which are the worst because they will climb a fence. Soy bean meal or extract, another high n source tends to attract mice, which wont hesitate to strip your lower branches. I prefer to attract the mice lol, at least there isn't a chance of total destruction, and the lower branches don't typically amount to too much anyways.
The year was started using only teas, but they just weren't getting it done. Ended up using all my tea mix mixed with soy meal as a top dress, which worked reasonably well. High n guano (Mexican I believe) also worked pretty well, but they just seemed to want more N than I could give them. It may have a lot to do with the organic sources not being readily available. Before considering synthetics, I had dreams of a custom made high N compost using all of the ingredients mentioned above.
