My first grow seems to be going south?

Took this just now. A bigger branch decided to lean onto this and break it off. I'm guessing I should be looking at flushing immediately, for the next 2 weeks.
Think the season will last until late October?

The only thing I can think of to do is to get some clear plastic sheeting to try to keep the rain off. Those look like they have at least a month to me.

I've been kicking that idea around for a couple weeks. I'm starting to get pm, so I think I have to bite the bullet on this one.
Seriously, I appreciate all the input!

I wish I could help more hahahah. I brought my plants in almost a month ago now. Of course part of that had to do with vacation, but I'm glad I did it when I did.
