Before you take action, are you sure its a magnesium deficiency? Purple stems and yellow lower leaves can be caused by other things as well.

Purple stems is most likely over watering. If you are sure it is magnesium, go to any drug store or grocery store and get some Epsom salt. It is almost pure magnesium. Mix a teaspoon to 2.5 or 3 gallons. Water once or twice then flush with fresh ph'd water then continue as normal. Be careful withe Epsom salt, don't use it more than once in veg and once in bloom, that is all you need.

It's not necessarily magnesium; nitrogen, phosphorus, and pottasium deficiencies can all cause the purple stems and yellowing lower leaves you're seeing as well. Can you provide pics and some more info?

I would look first at the environment of the plant, because, with a few exceptions, deficiencies are usually related to something environmental causing nutrient lockout, rather than an actual lack of the nutrient in the medium. The most common issues are - overwatering and ph problems. I've had magnesium deficiencies show up during veg when I grew in coco, but generally speaking for me deficiencies don't show up until the flowering stage, and the ones I've had during veg (growing in promix mainly) were related to the two issues I mentioned. Could you provide some more info on how you're growing?
