Fish fertilizer for orchids

Ok, I keep and keep reading everywhere about benefits of organic based fish fertilizers for orchid growth. Finally I decided to buy and try one.
Not much choice we have in our stores here, so I ended up with something called Muskie fish emulsion fertilizer 5-1-1 by Green Earth.



On opening the bottle I noted that it looks and smells really gross, hopefully small amount diluted in water won't stink that much...
5-1-1 is the ratio of nitrogen, phosphorus and potash in the contents of the bottle. I usually feed my orchids with balanced 20-20-20 ferts at quarter strength, so I don't think complete switch to Muskie will be good. I decided to alternate between my All purpose 20-20-20 and Muskie 5-1-1.
We'll see how it works out.
