Man, ive used so many forms of humic acid in my years of growing. So far i can tell you straight that Liquid Karma and Aptus startboost are the best ive personally used. Both contain L-amino acids as well.
Have you tried Tera Vita LC-10+7 or BioAg TM-7. I'd put either of those up against Liquid Karma any day of the week. If you really like liquid karma though, our local hydro shop has it on clearance (seattle area) for 13.50/quart or $35/gal. PM me and I can send you the shop.
My local farm supply gets their from these guys http://www.earthcrew.com/contents.htm I pay$11 for a pound and its dilution rate is 1tsp/5ml per 5gallons of water. (1ml per gallon)
I was told by someone that many nutrient companies use this particular humic in their supplements and nutrients. Ans some sell it exactly as it is just re branded.
I think you can get tera vita from simlicitea site

diamond nector by gh and the price is right too
I use Humisolve from BioAg.
Now I just need to get you to understand that Alex Jones is the hydro-store version of political pundits.
Seriously though, no reason to waste money, and especially no reason to waste money on guys who don't deserve it. Someone in the crew should do a cost analysis of all the organic and hydro products just to show how skewed this is. I really think this hydro store thing is a result of prohibition. If profit margins weren't so high because of prohibition, and if pot gardeners could go to legitimate garden centers for advice, these people wouldn't exist. When legalization comes you're gonna see all the bottle growers go out of business when they can't get a couple grand a pound.
