Well water

I don’t know what well water will do if I already have cal and mag added into the soil. Will I get nut burn?

You need to check the ph level , water is water unless you have bad well water

You have to have the water analyzed. If you have significant sodium or chloride you’ll need to do RO.

I doubt you'll get nutrient burn of any kind, but it would be good to know whether and how much cal/mag you might need to supplement with.

Now heavy metals are another issue. Cannabis is verified as a heavy metal accumulator, and many wells have heavy metal issues, not to mention other contaminants. I'd get it tested. They'll probably have a dissolved mineral analysis too, so that cal/mag question would be answered.

Honestly, if you're using soil you'll probably be fine whatever it is. What is your water's ppms? Even with coco most well/tap water is fine unless you've got some crazy alkalinity.

It’s 8.5 PH

Not sure about the Ppm getting a new meter and I will let you guys know

It probably has plenty of Ca in it.

I'm on a well and had to go to RO, I just couldn't keep my plants happy when I first moved and set up new grow. As soon as I switched to RO all my issues went away.

But every area has different water so you won't know for sure til you try it or have it tested.

im starting to use ro water, hoping to get aunit installed for next grow

I have decided to go with RO and add my own water soluble fertilizer and it also has all the trace elements in it. What do you guys think?
