Spider mite outbreak at very end of flower (harvest tomorrow!)

We are due to harvest tomorrow, and I just saw the telltale webs. I cut out the infected branches with webs, but I assume they're all over. It's my best crop yet and I don't want to lose it. Only 4 plants, and I cut out about 25% of one of them

1. Is there any way to clean the webbed flowers? If not, is it OK for ice-hash?
2. What about the rest of it? There are no webs, but is it safe?

Thanks.
