I just started flushing now in beginning of week 8 this has been going on for at least 2weeks but being stoned and lazy i´m really late to try to do somehing aout this. Still half the plants are in perfect shape and the rest seems to have big problems big brown/yellow stains and leaves reaching for the skies. I started flushing today ? is there anything i can try to do this late ?

thanks 4 any opinions

Naw, Cut the dead leaf off.
Flush it for a couple weeks. You will be fine.

sure are small buds for 8 weeks flower.
