Nutrient Burn Problem

Alright, im on my second time growing my last crop did great, this crop also great except one plant overnight it got major nute burn so im just wondering from the experts, when the top is limping down and only few stems still healthy, could I bring this thing back to life or just toss it?

Flush well, lower heat, (raise lights a bit) and be more careful next time. :thumbsup:

alright thanks man, ill post a little pic of my mess-up she's a doozie.:D
