What's the smell like on the original glue at the 4 weekish mark, i'm supposed to have a cut but it's just smelling like a normal sour kush or something at the moment, does it change at all.
Yup, that's exactly the smell you should be getting. As others have mentioned, it'll get more complex as it matures. I get sour, coffe/chocolate notes with a back end of fuel, diesel, or chem.
