been there, did that; I grew up in Alberta. -40 not uncommon.

I used a commercial soil: earthworm castings. I also use Flourish which
I believe has the other micronutrients you mentioned. In that tank the
red Cabomba is growing but the green never successfully rooted. I don't
measure pH often but try to maintain 6.5-6.8 with very soft water &
yeast CO2. You're right about it not liking +7pH! I also have a fairly
steady water flow from a powerhead which doesn't seem to bother it.
