Foliar feed with fish emulsion?

How do you foliar feed with fish emulsion? On the bottle it says
1. 2 teaspoons per gallon for house plants. Avoid welling foliage. (So how do I foliar feed if I'm supposed to avoid the foliage)
2. For outdoor plants, 2 tablespoons per gallon, apply to soil and directly over foliage. (so I can wet the foliage cause it's outside?)

How much per gallon? It's a 4-1-1 (all I could find)

don't go by the back of the bottle, use 1 tablespoon per gallon, for your plant. Spray her once a day until the yellowing improves. Trust me, I do it all the time but beware it stinks to high Heaven! Sounds like a great planting medium to me and that you found the 'root' (no pun indeeded) of your problem
