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.

Hi,
I use a whole house filter with our well water and still use the MSU fertilizer for well water. The only other ones they have are for city water and RO filtration. Regular filters take out some of the iron and heavy metals like lead. Your ph probably didn't change.

Hi Cathy,
Thanks for your help. After reading your reply, I think I'll just stick with the same fertilizer I've been using before my filter....same as you....MSU for Well Water.

Thanks again,

Filters do not affect the water chemistry enough to mandate a change in fertilizer.

Usually a change is only needed when your treatment technology removes the dissolved solids, rendering the water's buffering capacity close to zero. It take reverse osmosis, deionization, or distillation to do that.
