I cut whole plant hang upside down in complete darkness and 30% RH until small stems snap easy and the outside of the buds are dry then in the jars and "burp" them every day for 3 weeks but I can never fully get the smell out of the center of the bud... Any suggestions?
Yes. Next time, don't be lazy and do it right.
When you cut the WHOLE PLANT and hang it, it doesn't dry properly. That's what mass producers do because they don't particularly give a damn what they're selling as long as it sells.
Hanging the whole plant is not a good idea because the plant doesn't dry evenly. Much like a human being, the plant will attempt to live on and in so doing it will shut down flow to the outermost regions first, then the innermost last. So what you wind up with are the extreme outer parts getting way to dry from the get go while the innermost parts are still quite moist because they were still feeding on all the water left in that huge ass stalk (read as water reservoir) you hung up there with it.
Next time, break it down into much smaller pieces. One stalk is the BIGGEST piece you should ever have, and I typically even halve those as well.
The situation you have is directly caused by the way you hung the entire plant. It dried the ever loving shit out of the outermost buds to a point you screwed them up huge.
It has nothing to do with anything else.
Done the right way (my way) your plants hang for 3 days at 45% or so...4 days at most. They go into jars and are done a week later tops.
Edit to add:
and flushing is bullshit....just sayin....

Absolutely correct.
