Cheers - i've not much clue how hydro works/but found the relative information i understand definitely useful!All of the pro flushing society believe they get smoother smoke from “flushing” the excess nutrients out of the plant!
those that don’t flush know that smooth smoke comes from a good slow dry and decent cure.
a wise person once said you can’t remove nutrients from a plant by flushing copious amounts of water through its roots.
that’s a fact!
If you want to read what happens when plants are subjected to flushing of the roots then look towards tomato plants and what happens to them during a “flushing”
They end up getting fruit split!
RX green technologies have a study which is most likely one of the Studies @curious2garden linked.
what she, @curious2garden is referring to with an ulterior motive is that you’ve most likely not found any people that can provide you with anything scientific about why to flush and maybe just maybe want to invoke an argument which maybe didn’t happen in the last thread you made on the subject.
Now.
one thing I can tell you is that towards the end of the cannabis plants life it uses less nutrients to sustain its growth during the ripening stage of your buds.
personally I see a drop off of nutrient requirements from my plants once their main growth is done and in waiting for ripening to get to where I want it to be.
When I used to be hydro this would manifest itself in high EC returning back to the reservoir after flooding.
so towards the end of the plants cycle (around week 6 of actual flowering) I begin seeing EC going to the plants at approx 1.0-1.2EC pH5.8 and returning back at 1.4-1.6EC pH5.3.
this means the roots are using more water than nutrients to sustain their growth during that phase.
So I would adjust accordingly and reduce EC down to around 0.8EC and pH5.8.
this would then return back at approx the same level meaning that nutes and water are uptaken at the same rate.
With hydro you can track how the plant utilises the nutrient water based on how it returns back to the reservoir.
by doing this you’ll see that there is never a time where water only is ok as this process ends with nutes and water uptaken towards the end evenly at about 0.6-0.8EC plant size dependant.
Plant size dependant means my 2ft tall hydro plants aren’t using as much of the nutrient solution as my mates 5ft tall hydro plants.
Sorry to have rambled on but thought it pertinent.
If you have any questions on the above let me know but I’m no scientist!
Im not by any means invested in either side of flushing but more just what both have to offer.
@curious2garden 's link did answer my question asked in the previous post/thread - but there are other questions asked in the above semi related which is why i just reposted and edited no dam motive lol.
Ok so couple questions - whats EC haha?
Also - would chlorophyll break down through flushing besides nutrient deficiencies?
Also also - NVClosetmedgrower mid to late flower 38 minutes he talks about how after flushing the excess/general nutes out of the soil the plant leeches more back into the soil aweek later . . not saying i agrree or disagree but i am curious if anyone has a quick answer to it and would be genuinely grateful
