With the age of your plant, it's likely not this damaged from deficiency.
What soil is your plant in, what nutrients have you used, what type of light do you have and at what distance?

I wouldn't remove the dying leaves just yet. When I have an issue with a plant, I leave the unhealthy leaves as a baseline to monitor whether the problem has stopped progressing or not. I'll remove them after I've rectified the situation. Also, magnesium deficiency usually shows yellowing of the leaves before they go necrotic.
For the OP... what's the pH of the water and water/nutrient mix you've been feeding, and in what medium?

Are they from seed or clone? they are small to have that bad of a deficiency im thinking if they was clones maybe the mom was unhealthy. it does look like a mag deficiency to me but Ive never dealt with it outside of flower......i agree with spek9 leave the leaves for a base line...goodluck
