Going from green to brown is a sign of something happening to the chlorophyll, not necessarily the lupuline glands. With that said, I'd be pretty bummed about getting brown hops. My wet hops came from a LHBS directly from Hops Union. I used them about 3 days after picking (my estimate), and they were great, but the LHBS put them in sealed plastic bags for me, not paper bags. Maybe that is why they turned brown??
Have you weighed them to see if they are in lb increments as you ordered? Or have they already started drying out?
