I have not read it, but just lower the dosage of nutrients if growing indoors so they don’t are overferted when you harvest them. It’s cold outside (in many countries) which make the roots having difficulty’s to absorb and transfer them to the buds - so the plants are taking nutrients from their leafs instead as they have a closer connection to the buds. So the plants are basically “flushing” themselves.
Indoors, it’s normally warmer why most of us needs to bring down the nutrients the last week/weeks so that she slowly can use up the stored energy in her leafs.
But if you have underfed he’s and she’s tired and not full of energy it’s basically no point.
But with a correct grown plant I suggest, and you know it - that you can lower the dosage if nutrients in the final stage of her life.
I could go on but I’m a bit tired….
