How to higher the nitrate?

I have my 20L tank with CO2 about 3 bps, Lights about 7 hours per day, Dossing Excel 5ml daily, Flourish 2 ml every pairs other day, 1ml Seachem Iron every other day as well, Seachem Potassium 1 ml each 3 days, Wate change 1 per week 50%. Substrate Fluval Stratum.

Water Parameters:
PH 6.8 before CO2
PH 6.4 after CO2 by the end of the day
Ammonia 0
Nitrite 0
Nitrate 5ppm
TDS 238
KH unknown
GH unknown

What i am doing wrong? How can i raise the Nitrate numbers to archive 25-30ppm ??

If you want to stay with commercial products, there is Seachem Flourishs Nitrogen. However, a cheaper long term solution would be to purchase potassium nitrate

The macro nutrients for plant are nitrogen, potassium, calcium, magnesium, phosphorous, and sulfur. Iron is a micro nutrient. Flourish has essentially no nitrogen in it. i6 ie oleo w li6l4 lo3 in phosphate (PO4) almost no magnesium and calcium.

The common nitrate fertilizer is potassium nitrate (KNO3). I would recommend you switch to a better fertilizer like nilocg.com Thrive. With that you would not have to dose iron every other day or apply potassium. Basically you are using Seachem iron and potassium to try and correct problems in Flourish.
