Do i need cal/mag, CANNA nutes, R/O water

Do i need to add Cal/Mag when using Canna nutrients & R/O water. Using the soil line. It says "soft water" on the bottle. HELP ME!

probably too late now but, yes you do need cal/mag with canna/ro water

LOL I KNOW WISH U WERE HERE A COUPLE OF MONTHS AGO WHEN I WAS LEARNING THE HARD WAY!

but no cal/mag w HG though right? Its formulated for RO, correct?

Also, i THINK i saw somewhere Canna has hard water and soft water versions if im not correct? I know my bottles say "soft water" on them. Doesnt that mean they supplement for soft water? Im confused. I'm always confused i think?
