HELP! Flora Nova & RO

[Sosa]

When using RO water do i still need to add cal mag when using Flora Nova bloom in dwc or do i just up my base ppms? Is this just strain dependent or do i need to bring my water quality up to a respectable level with call mag first(200-300)ppms?

RO water needs cal-mag. Most store bought nutes won’t have enough calcium.
