First, Fix the water problems, then maybe add more or new swords. But as Rex said Swords get huge, when happy - well at least most species.
Swords are root feeders so you need rootabs. Best are slow dissolving ones made by Seachem available pretty cheap at Big Als online.
NPK are abbreviations for Nitrogen, Phosphates, and Potassium also known as Macro elements in the hobby. Trace elements are called Micro nutrients and are sold by companies like Seachem too. Or you can save a lot by buying it in powder form from Rex. You'll need to at least dose K if there are fish in there. Fish food and waste might take care of N and P and possibly trace elements. I highly recommend reading Rex's guide, it will solve many problems for you.
IMO, if you want happy Discus, I would spend the $200 for CO2 to lower pH and open plant options. Swords like soft water too as do most plants! But if you don't, then keep the light really low, like one bank per three feet (1/2 power) for max of 10 hours. And dose some K. You can buy the powder cheap from Rex or elsewhere. Its a common hydroponic fert.
Lastly, diatoms are a brown algae which are normal in a new tank. It shows up after 2-4 weeks and last a month or more depending on the tank parameters. Otocinclus catfish (little suckermouth) are terrific to wipe out Diatoms in a weekend.
