Dryer sheets

My last 2 harvests have had a dryer sheet or fabric softener taste to them. I run Super Skunk, Aurora Indica and Gods Treat. They all had their distinguishing flavors and smells but, with a dryer sheet undertone.
Everything as far as growing and drying rooms have stayed the same for almost 15yrs now. Same nutes, everything is the same.
Anyone have any ideas?

Plants growing next to dryer exhaust vent. Lol jk. No I havnt that's a trip especially since you havnt changed nothing your doing

I've experienced that in weed I've bought before, but not my own, no idea what it could be.
I've suspected mine was actual dryer sheets to cover the smell, but they weren't the kind of people who ever needed to cover up their stank, so it was really weird to me

Is it possible that some dryer air could have been close by is this maybe the soil or a mix that was put into the soil, how did the buds smell like when on the plant.

Dryer and exhaust are on the complete opposite side of the house.
I wonder if it could be in my Co2. I hooked up a fresh bottle right around a couple harvests ago. Just thought of that.
