At what level of GH does problems start?

We talking about GH 15 or something like GH 20 - 30? When is it too much and nutrients stop being available to plants?

Depends on the plants, I'd guess. I have many plants, my water is GH55.

I had a GH of 24 degrees, never had any issues associated with GH, KH is quite another matter.
