Definitely a low EC and why are you using hard water in DWC? That's a fool's errand.

Assuming your hard water has a high amount of calcium and likely iron. Read up on calcium excess.

If it does have calcium excess, what would be the best way to lower it?

Tbh it looks more like deficiency then excess, i've topped up the nutes to raise the EC to see how she reacts.

Calcium excess is a major cause of lockout in a lot of cases.

RO is always suggested by growers. Always for multiple reasons. Distilled water is perfect. Inert. Mineral free. Any bottled water beats what you are using. I believe most growers would agree. RO system is expensive.
