search Bio-Bizz grow + bloom, pretty reputable and 100% organic.
also, if you're feeling eccentric, go for the Canna Terra range, flores and vega.
for the grow and bloom together it's about $40, afew more for the Canna.
by the sounds of it, it would be hard for you to get hold of them, but check out some nutrient free grows, where they only use the initial nutrients in the soil all through the grow, and compare these with some grows with nutrients. they will dramatically increase your yield.
if you can't get your hands on those, you want to go for any vegging nutrient with a 1:1:1 NPK value, the ideal is 20-20-20, so if you find, say a tomato plant nutrient with 5-5-5, then simply multiply the strength by 4.
for flowering you'll want something high in phosphorous, so about a 10-30-20 NPK value, find something with roughly a 1:3:2 NPK ratio and multiply as needed.
remember 1/4 strength nutes in the first few weeks of using them.
