Be careful what you buy. Terrestrial plant fertilizers usually have urea as a source of ammonia that breaks down into nitrogen compounds in the soil. I would be willing to bet that hydroponic stores will have zilch for aquarium plants. You used to be able to buy stump remover with NO3 in it but since 911 well.. You're probably going to be buying it online..
