Nutrient burn during flower

OK, since you are seeing/smelling the difference, maybe it is too gone. My issue came as a case of 100% strength feeding. Did yours come to this state, because you were maybe feeding every watering? I would continue to flush, and maybe extend grow out another week or so, to let the plant use remaining nutes, from its internal structure. At that point it may start to get more CBD, depending on how your trichs are doing now. But it is better than bad tasting stuff. FYI, when you cure - - - > 3-5days to dry, then another days in a jar to cure properly.
