The guys in the big plants thread use it foliar and it's in the recipe for that discontinued "Brix-Mix", which was discontinued because the bottles exploded in transit. The company was kind enough to give out the recipe. You'll recognize most of the ingredients, the BRIX crew is on a parallel path I think. Credit goes to user rootzbelow,
"this is the recipe that PVFS sent me if you would like to make your own......
The following are the proportions of ingredients we used in our Brix Mixes
Feel free to change the blend to suit your needs and the availability of the ingredients. You do not have to use every ingredient for the mix to be beneficial. For example: if you don’t have Phytamin 4-3-4, you could sub a liquid fish or a dry fish powder, like HFPC hydrolyzed fish. If you prefer, you can use a liquid kelp extract in place of maxicrop. If you don’t have a trace mineral deficiency, you can do without the MB powdered chelates. Keep in mind that kelps, such as maxicrop, do provide some trace minerals. If you don’t have access to a liquid sulfur, just leave it out of the blend.

I was planning on doing a foliar spray of TM-7 today (1/4t/gal.), and decided to add some of our school of thought and the BRIX school as the above recipe was a little vague in doses and I don't have much of the ingredients. To the TM-7 I added 2T/gal of Neptune's Harvest fish fertilizer, 1T/gal diastatic malt, 1/4c(4T)/gal of aloe vera extract (I use the Lakewood brand, you want something without preservatives but remember to put it in the refrigerator once it's open), 1/4c(4T)/gal coconut water, and 1T/gal of unsulphured blackstrap molasses.
I was thinking of adding 1T/gal of either kelp, or a smaller dose of neem oil but don't want to introduce any more factors on a first go and would want to bubble the kelp for a bit anyway.
