Some just take longer to mature. The seeds description is just a guide not set in stone some strains can take 11 to 12 weeks to fully mature just depends. When did they start flowering
They look done to me.
Some plants take longer to finish. More sunlight during the day also equals bigger buds.
IMO let them go! I like couch lock though. My trichomes went clear to cloudy in a week. Rock on man!
I think this question is moot, looks like it’s been harvested already
Looks done if it’s cut down
If the humidity is high then you might want to think about harvesting… but looking at your girls as of now … I would wait at least 3 to 4 more weeks if weather permits… 
Maybe a lil longer honestly…
Alot of green there still…
Top post looks harvested already… lol…
That’s why I said they looked done. 
That was just a peace of it obviously if I said it wasn’t done
Chopping if not done alreadu
