My Plants Dont Smell anymore ?!

This has never happened to me before now , but i have white rhinos 2 weeks into flower (pistils are evident) , they did smell for a few days but now they dont smell like anything even close up, i find this very odd as the smell was there before.

The only thing i have done different is move one of my fans and directed it to blow just above the tops of my plants.
Anyone know why this is ?!

Dunno man,haven`t got a clue,wouldn`t sweat it just yet tho,its not like its into its last week and still dont smell....Patience Timothy,peace RM.

Rhino, keep us informed on smell thing I'm curious. as I have 3 WR's starting 12/12, mon-tue 10-2? Waiting for supercropping to take!
