flushing coco end cycle

any tips anyone wants to share?

i grow in pure coco.
i tend to start flushing towards the very end, around 55 or so, strains i grow typically go 70 or so.

my question, what is too much flushing? really just trying to produce the most flavorful flowers i can, and many times the flowers comes out nice just lacking a bit in the flavor spectrum.

i cut out N first.
feed p/k as well as some molasses and then go to straight water for like 5 days.

i know the strains i am growing should be way more terp filled than what i am producing.

It's hard to pull flavor out of coco. In my opinion it's all about your organic inputs ,beneficial bacteria ,and enzymes. Especially if you are on a salt based nutrient. I try to run as much organic as I can while still remaining hydroponic coco. I still yearn for a little more flavor as well.

i use tea, molasses, mammoth, photo plus, kelp

just wondering how to flush properly, smooth smoke and white ash, and still have the terpenes off the chart.
