Goodness... she looks awfully thirsty and certainly hungry... your diary doesn't indicate what nutes you're using but I would start feeding her at least 1/4 strength nutes (just adding nitrogen is not so good! she needs a good, balanced NPK nute for veg!). Drench her with water & nutes, and then don't water her until the pot feels very light and you know she's dry... Follow the water/feed/water/feed dictum and you should be fine! And btw, calmag isn't going to do much for her either... that's used to correct a calcium and magnesium deficiency! - she needs nitrogen, phosphorus and potassium at this point!)
Good luck with your grow!
