I have a quick question: How much aquarium salt is acceptable to plants?

It depends on the plants. Some don't like salt at all, some will grow okay
even in a brackish tank.

I have to say, my treatment of choice for ich in a planted tank is QuickCure or
Rid-Ich (something with a mix of malachite green and formalin). Plants don't
mind this at all, and it's very effective.
