Since high concentrations of certain heavy metals like copper are likely causing issues with plant health, and copper tends to be very high straight from tap water, I've been looking for ways to remove them from the water column.
I've found that Seachem sells a synthetic copper and heavy metal adsorbent called Cuprisorb. 100mL cost $10+. But from further research, there may be much cheaper alternatives.
Vermiculite, often used as a soil amendment and can easily be found at any garden supply store, is capable of adsorbing copper and other heavy metals. It's also used in wastewater cleanup. It's also really cheap.
I've placed some vermiculite inside a nylon stocking, soaked and rinsed it clean, and put it into my canister filter a couple of days ago.
Within just two days, I observed that Ammannia pedicellata "Golden" grew the most normal leaves it's ever grown before. They look healthy with no wrinkles. The fact that they are even growing is amazing! Rotala "H'ra" also turned a shade of red that I've only seen at Aqua Forest Aquarium tanks.

It's too soon to conclude that vermiculite is responsible for these observations or if it's from the lack of trace dosing but I'm optimistic.
