So I have my scale and I added up the parts and it came out to 26.2 parts. I divided that by 3.142 and got 8.34. I divided the 4 parts of Epsom salts by 8.34 and ended up with .479. Should I have multiplied the Epsom salts because I don't understand the answer. Maybe I need some B or Mn or something. I didn't see any Cu either. Huh.....I'm confused.
Does anyone sell straight N, P and K?

If you use grams for parts, you should get about 500ppm in 8 gallons of water. You'll have to experiment with it, but those are the ratios I use for my base mix. Generally I mix 2 doses of 26.2g at a time. Sorry for the arbitrary parts, that's just how I made it.
I have salts that contain B, Mn, and Mo, but stopped using them when I realized they don't make a difference. Same with Cu and Zn. You don't need those elements at all. Fe, on the other hand, is very important and i notice a huge difference when a Fe deficiency is corrected. (my mix is very high in Fe)

A more direct answer to the question from the original poster is this...
nitric acid (HNO3) is the only thing you can use that just has nitrogen in it.
Phosphoric acid (H3PO4) is the only thing you can use that just has phosphate in it.
Potassium hydroxide (KOH) is the only thing you can use with just potassium in it.
Calcium hydroxide (Ca(OH)2) is the only thing you can use with just calcium in it.
They're all acids and bases. The H+ and OH- ions form water.
