cannot find any hydroponic fertilizer, fish emulsion?

[Skill]

ok, I have finished building my system.
I found an outdoor timer at Fred Myers with 24 possible settings for $33.00 (Alaska prices)
However, due to my remote location, cannot find any hydroponic fertilizer.
What I did find was a water soluble organic (fish emulsion) fertilizer. My question is will it work? It's rated 5-1-1 .05% from ammoniac nitrogen .75% from water insoluble nitrogen 3.75% other water soluble nitrogen 1.0% phosphoric acid 4.0% chlorine Note: primary nutrients derived from sea going fish I'm thinking of starting will tomatoes. Will this work?
We currently are having about 20hrs sunlight up here in Fairbanks Alaska can I keep the feedings
round the clock under those conditions (Temp range 45-70) I'll be growing the in a green house.
