What is wrong with the face structure of my guppy?

Once a month water change is too low, make it weekly. I can't see how your numbers could be so low with that schedule. The growths could be a chronic reaction to the water, and some fish are more sensitive. Make sure your test kit hasn't expired (they can give bad readings).

That also reminds me of goldfish with overdeveloped wen that grows over their eyes.

The wen growth is from high protein diet not the water

Please re read my comment. I didn't say that was the reason only what it reminded me of because of appearance.

That strain is called a koi guppy and it has been around a while. Lately, a so-called “higher quality” strain has been going around that develops that head growth. I’m guessing it’s to emulate the wen/head growth of goldfish.

Amazing! Something new all the time. Look like little knobby heads.
