Loss of Smell??

Ok, here is the dealio. I've got some plants, some bagseed that is pretty decent. Ive made some clones and have plants flowering in different stages. I currently have a plant at 11wks flower and some others that are between wk 6 and 7.

Ok, so the plants that are at 7 wks have a real pugent, sweet order. Smells real nice. The plant @ 11 wks seems to have lost it's "danky" smell, although it still has some smell.

Ive been toying with this strain, since i dont have a scope and cant find one, on when the best time to harvest is. I took some at around 9 wks and i think they could have went longer.

Ok, question. Why this loss of smell? I consider mayself somewhat experienced and i actually just noticed this the other day. The buds keep growing and become rather large.

Has anyone experienced this before? The buds @ 9 wks smoked good, the others are still drying. I just don't get people.

Peace out.

i once grew a strain that didnt really have much of a smell till you sniffed it upclose or inside the buds wen we took it down then wen cured it just gave off a nutral/herby smell really with an undertone of ganja. could be down to the strain as it was bagseed u dunno do ya m8.
