Fertilizers... one over another?

In terms of fertilizers, is there one element that is better to dose than another? I'm on a limited budget so I can't rush out and get the full regiment. Here's what I'm working with:

29 gallon
ODNO lighting - two 24" 20W T12's in series (one is the GE Plant & Aquarium and the other is a 6700k bulb) at 4x ~2.5WPG
DIY CO2
Ammonia is 0 ppm
Nitrite is 0 ppm
Nitrate is 10-30 ppm (fluctuates, of course, but is usually closer to 15 ppm)
Phosphate is about 0.5 - 1.0 ppm
pH is 6.9
kH is 7
CO2 is ~26 ppm
gH is about 6

I'm currently only growing Anacharis (until my other plants arrive). They're growing fine under a short photoperiod. Longer photoperiods show signs of malnutrition. It's hard to say what I need, but that's why I am here.

Do you have about $20?

That's all you need for about a year.
