I think it contain too low portion of trace element(except iron) comparing to
PMDD or Tropica Mastergrow. Too little Zn, Mo, Mn, B, Co.

 According to Mastergrow's recomandation, you need 0.07ppm iron per week. I know
it depends... but 2.5ml per 55g(about 0.008ppm iron) would be fruitless, not to
speak of other elements.
 Another problem is there's no pottasium.
Unless you use pottasium-rich substrate, you need to add pottasium in your PMDD.

BTW, I improved DIY-lighting system of my small tank(30liter, 7.8g), from
3*10W(fluorescent) to 36W(biaxial PL)+2*10W(fluoruscent). Almost 8W per
gallon(small tanks need more light than bigger).
My liaeopsis starts bubbling.
