I don't know what my readings are, I've not checked them.
So liquid fert adds nitrates? Nitrates kills rams. Are the nitrates on fert the same that kills rams? If so, I don't wanna add liquid fert.

You cau use Flourish liquid and tabs (for crypts and swords). Api Leaf (iron and potassium) is good idea too. All that is not expensive at all.
You'll only need seachem flourish and api leaf zone. Add it as indicated on the bottle.
When you'll have the crypts or swords, you'll need the root tabs.
