AsNoriuanswered grow question 2 years ago I chased organic grows for 7 years now ... All nute company have that policy, stop feeding, let them grow ...
There no scientific proof, just one nute company made comparison...
You have to do long research ... And those myth as last dark hours, cold water, milk and etc has only personal preference THATS IT.
I can tell mine.
Was pushed to move out, had quickest harvests, with just few plain waterings before ... And that weed is still harsh after half year, no cure helps ...
Before i always had in SOIL 3-4 waterings plain at least, sometimes 4 weeks no feed, not real flush (did those too), but reasonable feed stop - does magic too....
