yo, you need to put those plants closer to your light. cause 70watts isnt much for our grows. i keep my plants 2-3 inches with my CFLs. not surehow you are doing it, but those stems look like they are reaching for more light.
for magnesium, use epsom salts (I got a whole tub of it). I use 1/2(or less) teaspoon epsom salts for every 1qt of distilled perfectly PH'd water. :D
EDIT: I did it, n my plants arnt dead yet. :P
