I have a white widow strain that doesn't start stinking until week 8 of flower. ...but after that it's like a dank bomb went off in the room.
Yeah mine started smelling by week 3 when they were small small still. Smell wasn't and still isn't terrible yet at week 5 Sent from my SCH-I605 using Grasscity Forum mobile app
I have a blue cheese that started smelling at about 3 weeks from germination. When flowering starts it's unreal. In late flowering carbon filters really struggle to keep up I just chopped a northern light blue and there was no noticeable smell unless you really put your nose to the bud, even right up to harvest
my tooty fruity stunk at 4 weeks of veg and stunk like crazy 3 weeks into flower my skunk didn't smell at all in veg and only just started to smell at 5 weeks flower
