When you transfer a plant from indoors to outdoors, you should do it slowly. Introduce it to outside elements a few hours at a time, every day adding another hour or two. After a week you should be good.
Your plant probably couldn't handle your climate, especially if its young yet.
Check out the outdoor growing forum to find any other info you might need. Good luck
I also just noticed, why did you give it plant food? You're gonna kill it dude. Its way too young for any kind of nutes. And Miracle Grow soil is not the best soil to use either.
