flushing isnt a myth
the term flushing is bad chosen
you want to feed just what the plant needs until its ripe and then feed the plant with water only which will dilute the remaining salts in the medium .. leading to better test
if you feed organic you will anticipate a wekk or two before ..
no broscience at all ... do the side by side and you will see
dont flush your plants in the shower with massive amounts of water, that is broscience
it will destroy your soil balance and lead to deficiencies/lockout
dont make yellow your plants during the flushing or before .. they must stay perfectly heathy and green till the end .. people make yellow the plant but i doesnt take out the P and K which are mainly responsible for bad taste ..
if you feed perfectly by checking the runoff an giving exactly what plants need you can grow great buds without giving straight water at the end .. but your product would be even better by allowing the plant to finish the salts in your substrate before you chop ..
more the plant go toward en bloom less it need N .. thats what your pk boosters are made for.. you want to change the ratio of your feeds by giving less N and more p and k
