I'm not a botanist so it might be a dumb question, but why does my bud, along with it's sugar leaves, stay green when the rest of leaves on the plant turn bright colors, brown or yellow from the chlorophyll being converted? Old buds that I find on the floor are yellowish. It seems to me that curing is mostly preserving the plant in an ideal fresh state. Also I've always noticed that the older the material the more amber my shatter is. My first run is almost always golden, and then it gets a little darker each time after that. Which is usually several weeks apart for a few months. Maybe oxidation is CBDing up your thc a little and causing it to be less harsh?
I'm not saying it doesn't mellow out a bit, but in my opinion the people who are talking mandatory weeks / months are wasting their time. My buds are harsh when the catch nute burn or are leafy. That's what I've noticed more than the length of cure.
