I'm still waiting ...
Oh great anti-vaxer science teacher
I'm vaccinated, but amazed that anyone would advertise such on a cannabis grow site; as though it were something to be proud of.
Got a bumper sticker too?. You're now on ignore feature.
To the OP:
I'll be happy to assist, as Rollitup has always had a rep as Trollitup...this section in particular.
Don't over-analyze, whichever poster mention lack of N during early flower is possibly the most accurate assessment.
I've had this condition, and he or she was correct in that no amount of N added will correct the damaged leaves; which you don't want much of at your stage anyways.
Best wishes on your grow.
