Calcium Deficiency Won’t Go Away DWC
So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

Started to get some yellow spots on the leaves, I think it is early Leaf Septoria. Any good recommendations for maintenance moving forward? How to remove and prevent from happening in the future?

Is this a calcium issue?
I noticed some discoloration on several leaves but not widespread. I think it is calcium deficiency but to make sure. Whatever ails her, a more informed opinion would ease my mind. Also, if it is a calcium issue, would raising from 3 to 5ml/gal of calmagic resolve it? (DWC)

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!
