Hi bro.... Sad to hear that.... Bit to be honest by seeing your plant it could have been worst.....
They will be really fine. leave them 48h in dark and cut them..... To dry.
For me... Flush is useless....(but its a non end debate)
Flushing wont change the taste of your bud..... Flush is useful only of you over nut them and u want to cool it down....
Cheers.
