Watering question........ I think im skrewed

so im growing outdoor for the first time, i have most everything set up ( holes dug, and the fence is almost up) my local hydro store sugested to get my water tested because i will be useing well. i get the results back and my water is extreamly hard! like a 10 . so i have a few options, i can truck some city water out, i can use some local spring water , or i can just use the hard water and get some nute that have 0 calcium in it.


what are your sugestions, i would really love your imput.

i always grew next to creeks and stuff and just used that water and it was very healthy! hope this helps

the outdoor grows around here do great and the river water sucks ass.
Mj is a weed and will grow anywhere the conditions
will let it.
