I agree with rusty. It IS a pH problem. You even answered your own question in your first post.

'Anywase, I did the trouble shoot on ph runoff water following stinky instruction....I would get 5.1 when in fact the ph water in my res. is 6.6 ...could this be the problem? Please HELP!!!!'

And like rusty said, fill out the troubleshooting form and everyone can get a better idea of what is CAUSING the pH lockout. Adding more calcium and magnesium will burn them at this point, not help.
