Thanks for the tip. None of those pics looked like it, so I will get a buddy with a camera over here this weekend.

I know the ventilation is bad. I ran out of money, but I will have a much better setup next month when I start over from scratch. It's been getting that hot in there for the life of the plants since they were seedlings and there has not been a problem yet til now - 5 weeks into flower. I did get a little nitrogen deficiency but it went away when I repotted with organic soil from the independently owned garden shop. No nutes so far.

Another detail I left out is the fish tank bubbler running in a jug of fermented sugar water. The yeast is old and dead and it smells sour. I need to make up another batch. The prob seemed to start when the yeast died.

Thank you so much for you prompt replies. I will post pics soon if I am able.
