I'm pretty sure I know what causes this problem when the obvious has been taken into account: the growing temperature, particularly in the last few weeks.
I've had a similar problem but by fluke I found out right away it wasn't the strain because I grew some both indoors and outdoors the first grow.
My outdoor would be dank and the indoor would be like cat food or some shit, tasteless. Still strong and get you high but tasteless with little smell.
I tried everything, all the stuff people already said here, proper flush different nutes etc etc and have come to the conclusion it's the temperature during growing, it's way too high due to my crappy conditions.
I think the terpenes are just boiling off in high temps while growing so there's really not much left by the time you harvest.
Winter weed grown indoors always tastes better and it's way lower temps growing in winter.
Also the LED growers often make a point of how much tastier and better smelling the weed is than when the same clones were grown previously under HPS and they often attribute it to lower temps as the LED's radiate far less heat to the plants.
It smells at harvest because it's got some freshly produced terpenes, probably keeps making them for a while after it's cut and hanging in the dark. No more heat burning them off so it reeks during the cure, problem is that's all there really is in it, anything produced while growing in the heat under hot lights burned off.
