How long have you had the Metal Halides on the tank? I used to see thin stems before I upgraded my lighting. The plants invested more energy into growing tall and getting closer to the light than growing robust stems.
Maybe you just need to give them time to thicken up under the new lighting. Or if it has been there for more than a month or two, this definitely could be a micronutrient deficiency. Your dosage sounds fine, though. How often do you change water?
