You are pretty much there.
It will only be a matter of preference now.
I personally like to harvest a little on the later side, so I would wait, but some people that chop on the early side would chop now.
I wouldn't worry about 1 day of rain if your girls are covered.
As long as it's not cool and overcast with high humidity for a few days after the rain, you'll be fine.
They are looking great by the way. You have done a wonderful job. Hope you get the reward you wanted after that risk!
