I have a 75g with Angelfish. I want to add some plants but my water is hard as a rock and the plants just die.

Try anubia. They tolerate hard water and are sturdy.
Bolbitis also tolerate hard water but may need more light and CO2 than anubia to thrive.

You could add Java Fern and Water Sprite are very tolerant of most water conditions.

I've also had good luck growing crypts in hard water. They're in softer water now and aren't doing quite as well. Plus I'm planning on breaking down my cryptocoryne tank soon and will have dozens. If you want to go that route, let me know.

Other factors such as light could be an issue. A tank in front of window takes advantage of sunlight. If using fluorescent lighting, the wavelength produced by phosphors inside tube needs to be in range plants can use. Intensity is another issue. After 3 months of cycled use, many tubes need to be changed out. Probably all fluorescent tubes should be changed out after 6 months.
