i agree, mostly, maybe i'm just crazy, but i do like to do a mini flush. when i think they have one week left i give them one good last watering with plain ph'ed water, then nothing till the chop. my logic is that by that point, they aren't going to benefit from any more nutes, but they still have some in their system. if i give them a good drink they can maybe use up what little they have left in a last spurt of resin and terpine production. not really expecting it to make them taste better or burn cleaner, just hoping for that little extra something. not sure if it actually works that way, but it doesn't seem to hurt.
But the true way to good tasting stinky buds is the dry/cure process, figure that out and you're golden.
