understanding something is relative; I've got a background in biochemistry; organic and inorganic chemistry; microbiology. over 4 years of it at university. I'm sure there are subjects you understand well also; granted I did well in the class. I was always interested in it. Professor tried to get me to change my profession and become a chemist.
Anyhow, it's all rather fundamental anyhow; and I've studied it for some time now. Lots of trial and errors made; and honing the techniques. Everything I do is mostly simple observation; trial and error. Tinkering; with ideas. Pushing it where I can; and leaving what doesn't pan out in the past. Learning from failure.
The real keys here are not everything listed in the pics. Most people have the microbes covered. The real benefits lie in having an simple amino source; a more complex ligand based one; and fluvic of some type. Those are really targeted buffers that enhance flowering. Build the buffer system. Enhance resistance. Feed the fauna, ect..
During veg I just use salts cause it doesn't matter; and the plants really don't benefit at that phase.
I only use it during the flowering stage; and the more "interesting" acids you challenge the plant with early in flower; the more it can do. Add a tiny bit of sugars for energy, and you've got yourself a truly "organic living salt" setup. Then just follow basic mixing protocols, monitor pH; and shazam.
I also alternatively flush everything periodically with a
Yucca saponin wetting agent; another layer of pH stability; to ensure proper drainage, and remove any excess buildup.
I'm paying literally pennies on the dollar for my solutions; and I contend there just as good or better than most of the big Ag companies offerings. Been there; done that, (very expensive) several of them; including AN and foxfarms; plus I can chase my micros far easier; and constantly fine tune things.
Here's the micros I use; if needed. This is one of the few formulations that I actually purchase. But this chelated micros will make 100's of pounds (dry) fertilizer. (1000's of gallons) Will take years to use up. $25 @1/8->1/16 tsp per gallon
