Flushing is not exactly BS but most growers do not understand the reason for it. And that reason is nothing to do with taste. The correct reason for stopping feeding in the last stages of flower is to discourage rodelization.

Is that even "flushing" then? To stop feeding just means to give water.

I don't understand how one would flush a hydroculture in the first place (i.e. when there is no solid medium to "flush" of anything).

You're correct. You can only "flush" a medium. I think what others try to do is "flush" nutrient out of the plant which is not "flushing", and does not work that way. Lol

Where does black ash come from...I thought black ash came from too many nutrients in the bud and feeding them straight water would force the plant to use any stored nutrients so the smoke would be smoother....please help me understand

Feeding straight water is... watering. Not flushing.

"Flushing" as it is commonly referred to means putting excess amounts of water (or mild nutrient solution even) through the soil in order to "force" any nutrients out of the plant. That is what a lot of people, including me, find to be laughable.

Also we're talking about "pre-harvest flushing". Intermittent flushing is a different story, if you are using mineral fertilizers there can be build-up in the medium, and it may make sense to flush those built up salts out to get to a clean slate. Mind you, in that case you're flushing the medium and not the plant itself.

black ash- how hot is the flame/is your pot dry/cured correct- so many people use bro crap to make up for shit grows and not willing to except constructive criticism.. dry and cured your dak correctly, may take 2-4 grows to get it sorted ....

There is no stored nutrient in bud, only leaves. You smoke leaves? Good drying and curing habits are what make smooth smoke.

So if I have no medium, there is no reason to flush? So I could run as high as 1200 ppm all the way through harvest?

If you have no medium, there is nothing to flush.

What would you flush in a DWC? What does "flushing" even mean then? The plant literally grows in nutrient solution, it is permanently "flushed", if you will.

In other systems, say ebb/flow, aero or NFT, one can replace the nutrient solution with pure water. That will stop nutrient delivery to the plant. Maybe you can call that "flushing", in my eyes it's just a change of nutrient regimen (from "X" to "NULL").

I assume, what you want is to make sure the plant does not get any more nutrients in the ripening phase, so it will use up the remaining nutrients in the bio mass, for a "cleaner" flower.

Just stop feeding the plants nutrients then in the final days, and see if that makes a difference to bud quality. There have been studies that suggest it does not make a difference, mind you (I have no strong opinion but I think the difference must be small or else this would not be a controversial topic amongst growers).

Whatever ec a plant is sitting/standing in will reflect in the plants sap, do you want to smoke raw nutrient residue is the question? it's all around the plants vascular system, give them water for a few days its reduced to 0.0

That is a fact anyone can confirm/test.

Reducing nutrients to zero in the ripening phase is not for dispute here. It's not "flushing", it's simply changing the feeding schedule.

It's great that you measure the EC of the plant sap. It's also a lot less scientific than you appear to think.
