Hard water confusion

Here's what confuses me. I keep reading that hard water stunts plant growth. It's supposed to be hard to grow plants in hard water. What confuses me is why. Hard water is just water with a lot of dissolved minerals in it. So how is it any different from soft water that's been dosed with fertilizers?
