Boy did i F*Ck up!

so....im like 2 wks from harvest..i was sick again and in somewhat of a daze, and i guess i must have mixed my ferts wrong or sumthin'cause i went to check on them 24hrs later and i fuckin cooked this baby... 50% of all the leaves r brown and twisted and crunchy...this was the last time i was gunna give her anymore ferts b4 harvest

my questions are

-should i just keep flushing
-how is this goin to effect harvest
-should i cut out the burnt stuff/it wont regreen will it?
-ohh my god i want to cry, i think im gunna have a panic attack
