fertilizer question

[VickiC]

Hi,
I initially posted my question below in the "Greenhouse Gardening" forum...subject "Water Treatment". I've started to wonder if I may have asked it in the wrong forum or titled my subject incorrectly because I haven't gotten any replies. If anyone here can help me, I would appreciate your advice.

Hi,
Until recently, I have been watering with our tap water that has a ph of 7.29 and additionally MSU Fertilizer for Well Water. I have now installed a filtering system in my greenhouse that simply connects to a garden hose which runs this water from our house. Garden Hose Filters I have a list of the water's mineral content that I was given at the water dept., but the list is extremely long and detailed and I have no idea how to read it. My concern is whether I should continue to use this same fertilizer or change to a different one. If I should change, could someone please tell me to what and suggest a particular product, if poss. If you need to know specific mineral content in order to advise me, please tell me which one(s) is necessary for me to supply you and I will try to decifer them from this list, if poss. Please feel free to PM me if you choose.

I would very much appreciate your help.
