Well any calcium magnesium (calmag) will work but really, I'd recommend getting a TDS meter first. Your tap water may contain those nutrients. I'd check with your local municipalities and get a water report. I found mine online with some investigating so start there. It's important to know what's in your local water if you're using it. If you're unable to find out use RO water as it's normally without anything added or 0ppm, then use calmag at half/normal strength. You may or may not have hard water. Anything over 60 ppm is considered hard, according to Wikipedia. I can't stress enough the importance of having a TDS (ppm) reader. Here is a link for a tds meter to give you an idea how inexpensive they are. You're a fellow CDN I assume?
See what happens in the meantime with the tap water. Good luck.
Yeah I might as well, they seem cheap enough like this one
If you are going to mix nutrient solution, a TDS meter is a good thing to have.
I have a cheap one like this, which has worked for a few years.
