Do I need calmag in dwc (pH tap )

See alot of people using calmag in in dwc and say it's essential .

I use tap and pH it ppm 250

You might, you might not. I'd start without and use if needed. What other nutrients are you looking to use?

I have GH flora series which ill go with and seems to be good for hydro . I have B52 and biobizz root juice but not sure in hydro

I've heard good things about the gh stuff, I ran masterblend when I did hydro sterile res, alot cheaper than the liquid nutes. Those other 2 look pretty decent though. Humidifier acid and vitamins. Probably gonna need to watch your ph closely with them.

Youll most likely need Magnesium before calcium which can be had with epsom salts,really cheap to.

Hard water? mostly full of Ca and Mg.Check your water data if your on a municipal water system.
