Imo gh booster causes problems... many rarer type plants love soft water.

If your using ro water, I guess a little gh booster won't hurt.

In that cause you would just use less, or none if you didn't need it at all. Why add something you don't need?

Without gh/kh boosters my ph would drop to below 5.0 if i add CO2. I hate my very soft water.

Most times, and more likely than not, you do not need gh booster. They cause many issues like melting especially for rarer abd more sensitive plants..

Soft water can grow both rare and common plants.

But not the other way around
