Did you reduce water/feed? Did you notice a difference in the one reaper you sprayed with epsom salt?
The first picture, there's still nutrient burn on the leaf tips, and it still shows Mg deficiency.
MgSO4 is meant to provide a quick supplemental dose to the leaves, but the source of the problem is still in the roots.
The fertilizer has a (22.5):1 ratio of Calcium to Magnesium. That's totally out of balance, and the Sodium content is also too high.
