Its not a good idea to use fish emulsion in your irrigation system. I am currently trying to find product that dont clog drippers so much. If you have the organic emulsion you still want to supply the plant with complex organic nutrients from another source. ie soil/ fert/
also you need a carbohydrate. ie sweet/ liquid karma etc..
oh ya ... you REALLY need to test ph even if its just with the dropper kits used for testing pools.
on the plus side stank box wont be so stank next time good luck
