I used seachem flourish for a while. Also used tank water from a high tech planted tank that was being fertilized by the EI method, this gave excellent results. But I am currently using Florin Multi. It has better concentrations that flourish and since I know someone who works for Florin, I found out that all their fertilizers are made from food grade or better materials. I am getting good results with it.

I wouldn't put it in a mister though, I only use fertilizers in my hand misters.
