Don’t worry, it was caught in time, ur plant will recover.
The affected leaves won’t become healthy again, but as long as the new growth is, you’re on the right track.
One last thing: 3 ml of Cal-Mag seems like a lot to me. If I were you, I’d start with 2 ml as a corrective dose, then go down to 1.5 ml once it’s resolved.
PS: Add Cal-Mag every time you water with nutrients (in soil: every other watering; in coco: at every watering).
