There are several points there to which I disagree.
I’d you live in an area where the mineral content is very high, an RO system is anything but overkill. Excessively high mineral content can kill a plant, especially if the water has a high alkalinity.
Don’t forget that orchids have evolved getting “nature’s distilled” water and that the mineral nutrient level in it are minuscule and only present for that first instant that a rainstorm washes them out of the forest canopy down onto them.
A decent quality fertilizer contains everything a plant needs. Sure, there are some that are incomplete, but why would you use them?
Remineralizer cartridges typically contain calcium and magnesium carbonate, both of which are important minerals. Yes, they work.
