All the info is great. I'm going to hit a few points.
Alaska fish feet might have knocked down your head from the oils. Oil of any kind is a foam killer. (take a beer with a head on it, swip your nose and stir your finger in the foam, it will be gone in a flash.
I've seen articles where olive oil wa added to the tea recipe to keep the head down.
I'd also like to add looking into using a delivery agent along with a wetting agent when foliar feeding. A delivery agent (which the only one I've seen for sale is by Dutch Master I believe) supposedly allows the nutrients (once taken up through the stomata) to penetrate through the cell wall. They didn't go into detail about how it did this but I've been doing some reading on the subject.
I found an article (that I will post) that talked about humates and their function in the food web and uptake/delivery of nutrients. One of the abilities of humates was allowing nutrients to pass though the cell wall. My theory is that in using a supplement containing humates along with whatever else you mix in your foliar spray, will allow the nutrients to penetrate deeper into the core of the plant. Any other info on this subject, please share.
A few articles that I really liked.

Loving the thread. Question though. I brew beer, and I was thinking of borrowing a concept from it. Tell me what you guys think. Facts, opinions, if you've personally done it....I'm thinking of a oxigonating the water right before I begin steeping. (same concept as in brewing to feed the yeast and get them started)
