I'm having this strange issue that is clearly related to the use of calimagic. I've been experimenting with adding calmag during veg to create a better multi strain formula. What happens is after a couple days the nutrients start turning brown, and the bubbles around the edge of the res get this brown residue that leaves stains where the water line is. I'm using ro water. I have had this happen while using jacks, and also while using cns17. The strange thing is that it doesn't seem to happen every time. I thought it was brown algae, but now I'm thinking it's fallout. I believe the issue is less noticable if i add the calimagic after the cns17. Anyway, it's really frustrating me. Any help would be appreciated.

Do you aerate your nutrient solution?

This is an issue with watering practices not calmag.

what are your rez temps? Are you using airstones?
I've been experimenting with temp. At this point I'm around 63 degrees. I do use airstones. I don't like to run them constantly so have them on timer to run 15min every hr. I really don't think this is the issue. The nutrients turn a shade of yellow/brown after adding calmag, then 1-2 days it gets darker and darker and little specs start to form around the res. I'm leaning toward iron fallout?

Forget the airstone. Put a small pump on the bottom of your reservoir to keep things stirred up better. It will also oxygenate the solution better than airstones.

the Fe in Calimagic is chelated by DTPA, which is highly stable until pH 7 is crossed into alcaline regions
Right. I've read that. This is why I'm confused. I'll post some pictures
