I think he still wants to dose iron, but wants to dose it less than the trace
would do.

You still need to add iron.

Flourite only provides iron to plants that are root-feeders. Many aquarium
plants don't have strong root systems and absorb most of their nutrients
throught their leaves.

In addition, some plants need more iron than just Flourite can provide. I
routinely give my swords, crypts, and lotuses root tabs containing iron and
other traces. Even in my 100% Flourite tank.
