IME, Anubias do fine with Excel.

Brown stuff that rubs off and grows back... Diatoms. They will go away after a short time.

I couldn't remember which common plant hates Excel.

My bad I was thinking of Anacharis
Per Seachem's site:
A. Anacharis is a particularly sensitive species (known to be sensitive to high temperature, trace copper, formaldehyde etc.). It is also sensitive to Flourish Excel. If you have Anacharis in an aquarium in which you are dosing Flourish Excel we recommend using Flourish Excel every other day rather than daily.
