my plant is burning HELPPPPPPPP

my plant is about 2 weeks old. It has 6 leaves. I use one CFL light on my plant. I left the light on for about 20 hours one day and when i checked on the plant two of the leaves were severely burned. One of the tips has curled a bit. I turned the light off after discovered this and gave the plant lots of water which it immedietly drained. What should i do to cure. here are some pics

It looks like it's too hot in there and it also looks like you overfertilized your baby. Do you have a fan blowing on it? What is the temperature in the cab with the light turned on? What kind, and more importantly, how much nutrients did you feed it?
