60ppm TDS tap water

[DoodleBug]

Hi all, first grow here.

My tap water is pretty soft, it's testing at 60 ppm TDS, is this so soft I need to add CalMag when growing in soil? Or should there be enough C/M in 60ppm water?

Thanks!

Depends... Are you feeding the plant, or feeding the soil? If you're feeding the soil, then no.. Soil should have more than enough calcium in it. If you are using bottled nutes that feed the plant, then perhaps, if none of your bottled nutrients contain calcium.

I'm feeding bottled nutes so will grab a bottle to have on hand, in cas e deficiencies show up. Ty!
