SOIL Entering flower week 6, without almost any smell 😬

[tut]

I have four good harvests under my belt but am baffled by this grow. Almost no smell now when entering week 6 of flower. The leaves around the buds are often not impressive with trichomes but they are there.
Is this going to be shit to smoke. Anybody got any ideas.
I am growing liberty haze from barneys farm.
