I know u guys probably arent talking about this anymore, but CFL's can burn plants.. but it wont look like that, it will be curling up and turning a bronze/brown color and it will be crispy.
you plant looks like its over-nuted and over watered, the only thing I can think of right now that might save them is:
transplanting them into a different soil mix, make it 50% soil & 50% perlite..
let the soil dry out a couple days, maybe putting a fan close so that it blows on the surface of the soil to help dry it out...
once you've let the soil dry out for about 3 or 4 days, feed the plants pH'd water with peroxide in it.
2 teaspoons of Peroxide is to be added for every gallon of water you feed them, but only ONE feeding, and dont water them again for another 4-5 days, or when the first 2-3 inches of the soil has dried out.
