Lost smell after curing

I just finished my curing of 4 different types,SD, NL, OG, GL… Had a decent harvest ,opened all10 of the mason jars for 5 min. three times a day for ten days.I notice that the loud smell it had slowly going away until the smell of each one is gone. Still gives a great head. What happen to the loud smell. Is it because no chemical were use during the growth. I used all of your grow booster during its growth.

How long did you hang them curing starts with drying so when you hang them should dry slow and sweet 6-8 days at temps below 70f keeping humidity around 55% some air movement but not lots and keep them in the dark. When stems crack but don’t snap then start the cure

Thanks . All in learning. Next time I’ll see.
