Backyard growers are the worst about stressing. The simplest solution is usually the right answer. Go out after it rains or morning dew and give each little shake. Watch for mold and harvest when they are ready.
Why is everybody in such a hurry to harvest premature bud. If you think they are ready, chop them but think about all the work you put into them this summer before you do.
That purple looks good but without better pics who knows if it's done.
