I'm going to try to go organic. When purchasing the materials for the modified Cornell spray, the only fish oil/ seaweed emulsion I could find was: Alaska Fish Fertilizer 5-1-1. The sign at Lowe's called it fish emulsion. Will this hurt if used in the modified Cornell formula?

Also, the ultrafine horticultural oil that I found was Sunspray Ultra-fine Year Round Pesticidal Oil. That is the right kind, isn't it?

Thank you for any responses.
