best flowering fertilizer?

I know the fox farms line is the most raved about fertilizer. But I am from Canada, most places do not carry this line of product. So what other flowering ferts have you had great success with? or heard from other growers? I'm thinking Canna is a good line or products. Maybe I'm wrong? Any feed back would be greatly appreciated. Thank you.

Are you soil or hydro? Organic or synthetic?

Soil. sorry I should have made that clear.

preferable organic

Then use guanos, worm castings, mushroom compost, etc. I think the best way to do organic soil is to follow a complete soil recipe that only requires water. If you do that you don't even have to worry about PH.
