Adding calmag to soft water

knidik · Jul 11, 2023

Hi,

I'm growing in Biobizz light mix soil. Never added Calmag before because water in my city was hard. Here it's soft : tap water EC is 0.1.
Should I add calmag to every watering ? Right now they're week old seedlings. We grow other plants and there are no signs of calcium deficiency. But they're not cannabis

Thanks

Ps- they’re looking good so far

How long have you grown other plants with this new soft water?

Do you have an in-home water softener? If so, many of those (like the Culligan in my house) use sodium based products and the water long term is not best for plants.

Other plants (habaneros) are outdoor and have been there for 6 months. They’re thriving.

It’s naturally soft water, it just goes through a sediment and activated charcoal filter to filter out dirt/unwanted stuff, but doesn’t filter any minerals.
