Also if youve any room between your soil and the pot, fill the space with clay pepples or perlite can help to deter creepy Crawleys.

If that is a pre-amended soil, it's highly unlikely you have a magnesium deficiency (or calcium for that matter). If it is mag deficient, it's likely due to improper pH.

It's definitely not an issue with your light, as the lower portions of plant are burnt up too.

It's more likely pH related, or over fertilization. You need to adjust your feeding levels and or pH. Using 6-7 pH water, and making sure your pH remains in that range after adding nutrients (at a lower dosage than manufacturer recommends) is vital to plant health and nutrient uptake.

Look into compost teas.. you'll be able to water your plant, and give it some needed nutrients, without harming it while its healing over the next few weeks. Compost teas can do exactly that. It wont completely heal necrotic areas, but it will help rejuvinate your plant and give it back some vigor.
