Well, those may be great for growing pot, I mean tomatoes, but the plants don't need the micro nutrients. Stick to macro nutrients, because zinc and copper are toxic to Nepenthes. Using a fertilizer with micro nutrients, as long as it does not list zinc and copper on the back, is probably OK, but you don't need it. AFAIK no one has done an experiment on that yet.
The good news is that that stuff is probably expensive, and you can use regular Orchid fertilizer or fish emulsion. Many people use MaxSea and/or Neptune's Harvest. I use Alaskan fish emulsion, personally.
