I have the same problem. I chopped 3 autos a while ago that didn't really have smell after. They were so strong like sour berries then I chopped and no smell. I was thinking I did something wrong. It took a week to dry with an damp jarring with constant burps. Until just right. But no smell.
Anyways chopped a crappy white widow cuz I had it so long. The plant was maybe 5 months old no taller then a foot. Was stressed like crazy. Was trying to get fem seeds from it outside. But I don't think it got enough light. Got 20 grams from it no smell another 20 grams or more I couldn't use since it was sprayed with cs .very slow dry...
Don't really know. If my house is too dry or what.
