Foliars I use - Lavender Oil, Rosemary Oil, OHN [my own recipe.], AACT Diluted. and Coconut Water / Aloe Diluted
I rotate them around and end up spraying 4-8 times a week. The plants seem to love it.
If you're interested in any I'll happily give you the recipe.
I do not use KNF's exact formula for OHN, but the resulting mixture is something the plants seem to like a lot more -- I've used both. Some nerds got furious with me over this yesterday. That's why i'm explicitly stating.
