When I dry/cure my weed, it will 'feel' crusty on the outside, due to the exterior pores drying ahead of the small amount of moisture trapped inside.
At that time, I often place it in air-tight or close to air-tight containers over night or for the day, then when I feel it again, it's evident that the moisture has equalized, and the buds are typically uniformly 'damp' (not typically truly wet, but damp). I then place them in the drying trays again until they are feeling 'superficially' crusty again.
(Note: my drying trays are not open to free-flow air after about day 5 of drying, +/-, before I close them to limit ventilation, where they are slowed in the process a bit, and partially rehydrate from semi-trapped moisture, due to the reduction in air-flow, though not the same as when I do the air-tight or close to air-tight over-night containers..
Depending on oil content, I may have to do the temporary containment and rehydrating 2-3 times before I get the moisture content where I can feel right about placing them in their final containers for curing, what ever those containers might be.
Rarely had anyone take issue with my drying or cure.
Learned a word years ago, 'homeostasis', that taught me that most to all environmental variables in a given environment seek to moderate or equalize with each other; heat seeks cold, cold seeks heat, moisture seeks dryness, dryness seeks moisture, etc. That's more or less what you're dealing with when you have the sense of superficially dry exterior but moisture trapped inside them. Given the opportunity, by containing them briefly, you can expedite the release of the 'trapped' moisture by providing that environment temporarily.
DON'T place them in air-tight containers until the WHOLE bud is equalized in moisture content, and low enough in moisture content to not become a petri dish lab experiment in fungal growth.
Don't know if I made any sense with that. It was a long night...
By the way, don't beat yourself up so badly. It's a precursor to falling prey to past self-destructive habits. If I had a dollar for every time I screwed up, I'd probably be sipping high-end tequila on a white sand beach in remote Central America, with gated security, or making shapes out of clouds while laying on a grassy hill in the mountains of Nepal..
