WDreanged it seems as though you dried too fast, once the flower is dried past a certain point it is to my understanding there is no going back. The flower's metabolic processes have stopped because now it is dead. The metabolic process(photosynthesis) is what breaks the sugars and nitrates down to water and CO2 (the article posted above is excellent). This is what happens when you grow, screw something up learn from it and do better next time. Any grower on this site has ruined or screwed up a crop at some point.
Curing is an inexact science with many variables every grower has to start somewhere then adjust to there specific environment. The safest and easiest way is to hang dry, then put into paper bags with strips of paper bags separating layers of bud, then jars, the key to this is when the buds go into the bags they are not dry, the stem snapping is one of a few things to look at, the overall dry feel of the outside tips especially, and dont wait for the big stems to snap the little buds will get dried out. Get a cheap hyrgometer (online or cigar shop10$-20$try to find the smallest possible) or two and put it in the jars with your buds, try to put similar size buds in the same jar have one jar with big buds and one with small use these as control to estimate the humidity in the rest of your jars. It takes around 24 hrs for the buds to reach equilibrium, then check the meter 70% or higher is too much mold will come, put the buds back in the bags overnight or longer, i like to start my cure around 65% for mold prevention but i have been told 70% or lower is fine. Once your happy with your starting point the goal is to drop humidity 1-2% a day until 60-55 %, control the drop with burping, i believe below 55% humidity is when most plants start officially dying (metabolic processes stop). The key to this whole process is SLOW!!! 1% a day is better than 2%, always keep them in the dark, and no direct fan while drying.
Hang dry 3-4 days (dont let big stems snap, dont over dry)
paper bag 2-3 days (i usaully go 48hrs then check moisture with hygrometer)
Make it a scientific process take extensive notes, start with a plan and adjust plan according to outcome. i.e. start burping 2 times a day for 5 mins, do this for 3-4 days, takes notes every day of any changes, if the jars lose more than 4-6 % humidity slow down burping, if less burp more. Also consider the different size buds in different jars, small buds are likely to dry faster, take notes of the difference.
