KH of 22-23?! 
I will assume your kh measurement is correct, if you have any doubts, test it out!
OK, you're going to have to work with that one. One of the first things I would do is determine your individual Ca and Mg levels in your water. If you're on a city system, they should be able to provide you with all the info. If you're on well water, get a Ca test kit for fresh water, and find out. It's a little odd that your kh is that high and your gh is so low. Because high kh is usually a result of a limestone aquifer which will have high Ca readings. Having hard water myself (kh11, gh12 - though that doesn't sound high compared to yours), from personal experience, I add Mg (epsom salts) because most all the gh is from Ca.
As to your schedule, I don't think I would add macros 3x a week. On my tanks, this is what I do: add 1/2tsp Mg, 10-15ppm NO3, 2ppm PO4, and the recommended K after water change. Mid week add half as much NO3 and PO4, no K. I add micros in the days in between.
If your kh measurement is correct, be patient with your plants and tank. Because you will have more issues than most getting that balance started and you will have some problems growing some plants, while others you won't even want to try. Us liquid rock folks have it a little harder. You might want to look through this thread.
HTH.
