Nute burn late in to flowering!!! Help please..

Hey guys, Im a noob to all this so help would be greatly appreciated this is my second grow. First grow was going perfectly with a feminised seed I purchased in Amsterdam until it turned out to be the 1 in every hundred feminised seeds that are male And I had given the other four I bought away to people... Absolutely raging......
So here's my latest dilema. Managed to get my hands on another seed its Kaia Kush. Im running two lights a 250w HPS and a 250w MH using a cool blue bulb through the mh and a red flowering bulb in the HPS. Everythin was going fine until I left my plant to be attended by a mate as I went away for a few days and the dopey fuck (he's my mate I can call him that) burned the shit out of my little lady his excuse being "I didnt know how much to feed it so I just threw in a few scoups" even though I had told him just to give it plain water.. Anyway whats done is done his bruises and cuts will heal a few stitches never did anyone any harm
So back to my problem anyway, now I have a badly burnt plant thats 9 wks in to flowering but for the 2 wks it hasnt grown in the slightest. Buds are remaining small with only a minute amount of triches turning amber. Last night I felt there had been a small bit of growth. She's not goin to die is she???? Im not sure if I will be able to handle that.. All I want is to be able to grow and smoke a little of my own herb. Too much for any man to ask for?????
Anyway help or advice like I said will be greatly appreciated..
Cheers guys..

At nine weeks most strains are about done with flowering, but it's hard to say with out some pics. did you flush the grow medium a few times with plain water?

flush flush flush, with that amount of nutrient added in you've probably got enough in the soil for the remainder of the grow...give it nothing but straight water and it should perk back up and finish itself out

On the bright side, here's 64 pages of "experts" arguing that their is no such thing as over fertilizing your plant. LOL

Cheers for repylin guys thats what I figured and yes ive been just flushing it with plain water ever since. The blatant stop in growth is prob just to do with the plant going in to shock right??
Im flushing every 3 days at the moment. I will try take a few photo's later and post them. From forums ive read and videos ive seen my buds seem a long way off..
