You should stop showing your ignorance on topics you clearly have little understanding of re "hydro ... lacks the accuracy and leads to unnecessary excess the fate of which can end in plant tissue." Yeah although you can finely tailor a nutrient regime in hydro because all elements are readily bioavailable whereas in soil organic growing it lacks the necessary control because of the need for microbial breakdown and hence unknown quantities. You just stepped right into the idiot pooh. What you are talking about is luxury feeding or feeding to excess which many novice hydro growers do; however, that is a statement on growing skills and not hydroponics.
This is about flushing
I am calling you out for cock blocking a discussion that goes into the uncomfortable area of the differences between hydro and soil interactions without saying or or the other is better. That is the issue. Flushing is a lame duck term taken from old soil container method logy so it never applied to hydro. Only no nothing noobs carry the term like a torch.
However the fate of nutrients in plant tissue does vary powerfully based on methodology. All methods suffer from poor understanding in this manner so there is no superior to be had in this discussion.
Just tons of fear because people are out of their comfort zones and get defensive. I'm not fucking stupid and you are all very easy reads. Wear a kick me sign it would be less obvious.
Anyone adult enough for a productive conversation yet?
