Looks like calmag to me, if you are ONLY using terra veg from cana it could be, its just a simple grow nutrients with some NPK, not containing all the micronutrients, i should try other nutrients with a more complete range of macro and micro nutrients

Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.
