From the pics I dont see anything unusual.

There aren't many options here, but I suggest you burn small portions of these buds in bowls with hollow stems attached, or rolled in paper.

Again I’ll follow mystic- put a flame to it ! Lol
We don’t see anything from the pics , if it were let’s say gray mold when you break apart the bud you may see some dust fly? Or it would look more like a web

BURN IT WITH FIRE

How do they smell?

Pic 1 that dark area on the stem is concerning. How'd it burn?

It looks OK to me.

Update: I guess I could be a bit paranoid….but my buddy just looked at it through a microscope and did not see any mold. He smoked some and said it was smooth and had no taste of mold….and the buzz was quite nice and even.
As for the question about how it smells, he seemed to think it smelled fine and would get better as it cures more.
My nose isn’t the greatest and I guess I may have been expecting a stronger and more pungent smell. At one point in this endless grow the smell was phenomenal…but as the mistakes happened the smell decreased.
This grow was a great experience but it was also filled with issues, many of which were from my own poor decisions and mistakes. I stressed the plants too much and defoliated too many leaves and did so way too late into flower. This killed off many of the remaining leaves and caused a major problem at a crucial point in the grow. These were autos and weren’t chopped until weeks 19 and 21 respectively. The three plants (from the same seed pack) couldn’t have been more different for being the same strain. They began re-vegging for a short time and never did produce many amber trichs….I waited and waited until I couldn’t wait any longer.
i don’t know if there was the beginning of some bud rot or mold present at harvest, but I did see some brown calyces at the base of each stem internode….the ones that grow solo in the “V” of each stem. I don’t know what u call them but they were definitely brown and would pop off easily.
So I’m guessing if I, as the grower, would have did a better job the buds would look, smell and taste better.
All in all, I have about 7oz from three small plants that I didn’t have when I started.
I hope to do better this next run and having you fine folks as a resource makes me think I will.
