I believe the vast majority of dwc growers use CalMag

Yes but test to see what it's doing to the EC of your base nutes first!

I'm asking about organic calmag specifically

CalMag is pretty much a must, especially if you're using RO water. Test the pH of your base water and then add enough cal/mag to raise it to between 125 and 150 ppm, then add your nutrients.

I use the old kind still, not sure if it is still available. The one without any nitrogen added. I try not to add it if I can help it. I use filtered tap water, and it's at 80 PPM 7.2 to 7.4 pH. Both Green Planet and Advanced Nutes have had issues with it when adding calmag to an existing rez, just watch for pH spikes and you should be good. If it's a fresh rez, it's never an issue. Adding calmag first is the best advice.

I use 0ppm ro water. Add 150 to 200 ppm .500 scale of calimagic by general hydroponics. If your measuring in ec. 2 to .4 is ideal then your base nutrients. Then additives. If using a silicone like armor si from general hydroponics you always add that first before calmag then base nutrients then additives. Then ph. If running sterile you want to run your system with h202 or Dutch master zone or whatever you use, if you use hydroguard or Bennie's let your res bubble and mix well after you oh the water so that the ph up or down doesn't kill the Bennie's when you add them. Let your system run a hour or 2 before adding hydroguard or bennies

Lol... everybody's baked! The question was specific and nobody answered.

The question was... can I use ORGANIC CALMAG.

You didn't specify the brand or that it is organic, which is why you got the answers you did.

There's no pic in your post or mention of what brand and product your talking about
