you can always use fish emulsion, earth worm castings, bat guano, kelp, blood and bone meal, etc, etc if you want to stay with organics.. there are plenty of organic tea recipes online, or check out skunk magazine if you can get it around you...
if you don't know, skunk is like high times, but way better imho, less commercial and more about the smaller guys... anyhoo's, the one guy who does a lot of articles for skunk, the rev, he's an organic freak, and therefore there's tons of info in each issue of skunk about tlo, or true living organics..
or you could always go over to either matt rizes veganics thread or subs organic thread on here, i'm sure they are both full of good info...
