You are just wasting your time sprinkling Epsom salt, you need to drench yellow dying morning plants with magnesium sulfate water, 1 tablespoon per gallon. Do this every 3 days for 3 days
Watch the results! Learned through experience don't overwater! Your potted soil doesn't need all the stuff on the top just use good soil like black gold with fertilizer, it's up to you if you want to listen.
