You can always save your girl... if she has a sturdy healthy stalk and her roots are good... she'll be ok... just don't freak out and do too much to her... if you flushed just make sure your soil isn't too wet...give it some breathing holes right down to the bottom. I don't care what anyone says, it helps with air circulation, you could have a beautiful plant and boom something goes wrong with her roots and it's a wrap. Just make sure next time you don't fert. I would water it the next couple times.... she'll be ok. New growth is always a sign of life, I have a plant that is very injured and she has new growth everywhere and people see her and say damn... LOL... I'm like she'll be ok! Good thing to do also is if you have large plants make sure roots aren't blocking your drain holes, use something to unblock them to make sure your soil is draining properly or you could get root rot and other nasty things in the root system. Good luck....
