Well, after a little looking I came across this online calc. vs using formulas.

http://green-drop-home.com/orchidswp...zer-solutions/

According to the calculator, a 20% nitrogen fertilizer at 1 tsp per gallon should yield a Nitrogen PPM of 264 and a TDS of 599. 1 TBSP would yield a Nitrogen PPM of 792 and a TDS of 1797.

So my method of measuring the teaspoons earlier were quite faulty. Evidently.
