Mark, I was at a talk last month put on by the guy who ran the trials in your link. He now works for a fert company that has some interesting stuff. Lots of biologicals and chelated stuff like chelated mag. He says chelated mag sulfate is superior to regular mag sulfate and can't believe hydro-gardens doesn't mention this.
They are really big on the silicon too.
The have a product the basically combines rootshield, actinovate, and companion into one product. Also has humic acid, kelp, sugars, and amino acids. They really remind me of the stuff that Aptus was doing in the info you sent last year.
I just got their recent newsletter that had trial results from 2016. Brandy Boy was the champ with 44 lbs per plant. That is in a high tunnel. All the other plants were 20's to low 40's too. All treated the same, just different varieties.
I'll see if I can post it somehow.
