what's my target?

I tested my chemicals tonight (still trying to understand the baseline measures) and my P04 is 5.0 mg/L.

The Hagen test kit does not say what I should be shooting for in phosphates. Perhaps I overdosed on the macros today (added 1/32 tsp dry - just started dosing). I'm assuming it's high because 5.0 is the last measure on the evaluative chart.

In fact, what should all the targets be? Here's what I THINK they should be, am I on target? Note, phosphates here are 0.00000 versus 5.0

pH 6.5 to 7.0
KH 3-6 degrees
Nitrate (NO3) 5ppm-10ppm
GH 2-8 degrees
Iron (Fe) 0.2ppm to 0.7ppm+
Phosphate (PO4) 0.2ppm to 0.5ppm
Potassium(K+) 20-30ppm

Should I do an extra H2o change to reduce if I'm not aligned in the target perameters?

The rest of my readings:
PH 7.0
KH 60 ppm
GH 200 ppm
C02: 10.2
No3: 0.1

Here's a guideline of nutrients that should be in any planted tank.

CO2 range 20-30ppm
NO3 range 5-30ppm
K range 10-30ppm
PO4 range 1.0-2.0 ppm
Fe range 0.2-0.5 ppm
GH range 3 degrees ~ 50ppm or higher

No need to do a waterchange.
PH is okay, just make sure it remains stable within a .2 fluctuation.
No3 - Needs to be higher
K -
Po4 - is high, no need to dose again (in case you don't know mg/l = ppm)
Co2 - could be bumped up more if you have pressurized, but if not it'll be okay.

Remember this is an estimate of the nutrients in your tank, so don't get hung up on getting perfect.
Some people dose heavy once at the beginning of the week, and by the time the next water change comes about, the parameters are reduce from the uptake of the plants. So you'll be okay if you over do it alittle. Just test before you dose again, to be sure you need it.

Best of Luck!

I would follow what the kidd mentioned...no need for a water change, but do get the nitrate up!! Also consider adding more yeast to your co2 solution...the recipe I have my GF was 2 cups of sugar, 1/2 teaspoon of yeast and a pinch of baking soda...that gave her a constant "pop pop pop" of bubbles going into her aquaclear impellor for about a month (about 25-30 ppm co2)
