Cannot get to wilt stage that late it flower… if underwatering is the issue. They can bounce back that late.. just slow

It looks like it went through a severe dry back period

I’d be checking those trics. See if it’s able to be harvested. Late flower and being that pissed off id be thinking herming potential. Looks like you forgot to water for a pretty long period? A lot more info would be needed if it wasn’t due to not watering for advice.

Looks like bad water, maybe use a rv filter
