Hope you dont mind if I add to your post ... was going to do one of my own then realised we have the same problem

Ive got Ionic Grow, Ionic Bloom, and Formulex. Up to this point I have been using formulex, but I am wondering when i should switch over to ionic grow?
Also is there any way to tell whether its Ionic for Hard Water areas or not? And If not, is it okay to use hard water, I should imagine it would just be a little more difficult to even out the ph to desired level...
Thanks for the help
