Bud Rot? Or?

I could sure use some help diagnosing this problem - the buds looked like normal purplish kahunas at first - but they are getting darker and darker.

I removed these from the room (indoor) - what do I do to keep the rest of the plants from getting this?

Thanks!!

What's the humidity in your grow room...............?

Get a dehumidifier(I have 1 right outside my grow room).....add some fans.....and get the air circulating better.........
