she looks a bit light (but that can be due to the picture), but all in all quite healthy..
have you given her any other nutrients, other than calmag?
Calmag is usually less required when using tap-water (unless there are clear deficiency signs), as normal water already has some calcium (which makes it "hard"), and it's mostly required when using reverse osmosis water (RO water), as this filters out all existing salts, and therefore also the calicum and magnesium which then needs to be re-added..
The medium looks like coco to me, so i would assume you have given her a regular feeding as well, right?
all in all she looks nice!
happy growing!
