Different mediums/nutes require different flushing techniques. With Canna in pure coco coir I can feed up to the last week, and if I stop feeding 2 weeks ahead the plants will stop growing. I'm at the point that I don't flush the pots with water, but just feed it plain water for a 7-10 days and the plant will turn out great.
It comes down to the CEC (cation exchange capacity) and a few other properties on how much the medium will hold onto nutrients, and exchange them with the plants/flush out. Its much higher in soil, lower to zero in hydro. Your plant needs ~week to deal with the nutrients its absorbed, provided new nutrients are not available to the plant.

2 not 4, sorry if I'm confusing, I'm on a bit of acid at the moment and I guess shouldn't be using the internet if the numbers one threw four are too hard for me too discern.
WoW....I can't believe some of the shut i just read here! And we're the screw ups?

I don't think it was acid, I think you said something wrong and then backtracked really awkwardly.
If you're growing in a medium with a low cation retention and exchange potential then even a 1-week flush would be sufficient. The plants consume the stored nutrients almost immediately from their interstitial fluids, you're basically just trying to flush the nutrient residues from the ionic retention points within the growth media.
And that my friends, is my first post in a Cult forum in way too many months.
