The results below are a total of one dose of each fertilizer you're using. Since your are not using CO2 injection most of the doses seem okay. Everything seems to be around half the full EI dose which is fine without CO2 injection. The only change I would make is increasing the Plantex and EDTA iron doses to 3ml. That will effectively raise your iron to 0.25 ppm per dose which is about 1/2 of the full EI dose as well.
(x1) KH2PO4 10gm (approximately 1 3/4 teaspoons)
(x1) K2SO4 40 gm (approximately 6 1/4 teaspoons)
(x1) MgSO4.7H2O 60 gm (approximately 11 3/4 teaspoons)
(x1) Plantex CSM+B 15 gm (approximately 3 1/2 teaspoons)
(x1) EDTA Fe (13%) 10 gm (approximately 2 teaspoons)
The levels above are for a 15 gallon tank using a container size of 500 ml and a varying dose size.
