As you can see from the pics the stems of my plants have turned a purple color. This same purple color shows up in the veins of the leaves. When new leaves are being produced they will almost immediately show signs of the brown curled tips. I read up on this and figured it would most likely be a magnesium deficiency(?). I'm running a bubbler system with my reservoir holding 13 gallons of nutrient solution. How many tsp of epsom salt should i add to make up for the deficiency?

Is there anything else I should be looking for that may be a problem as well??
