I strongly disagree with this way of thinking. Granted, the plants have no way to expel excess nutrients but cutting back or eliminating nutrients near the end allows the plants to utilize any stored nutrients and only uptake water and/or water and cleansing agents. I've done it both ways in organic soil, soil less and hydro and plants that have been flushed always produce a product that is less harsh and smoother to smoke. I've also discussed this subject with representatives of both House & Garden and Cultured Solutions. To the man they all agree that cleansing the plants near the end product a better product. Since they know more than I do on the subject, I'll take their word. As I said, my own experimentation backs up what they have told me.
They're your plants, you raise them however you want.

I will always be honest with new growers on the basic science of plant biology and let them make up their own minds.

While you may see it as being honest with new growers, I see it as passing bad information to growers who are trying to learn how to do things correctly. Flushing, or cleansing plants, is settled science as far as most growers and nutrient producers are concerned. My own experiments over the past decade have backed up what the experts have said. Tissue analysis has shown lower amounts of stored nutrients in plant tissue when flushed compared to plants that have not been flushed. Some people don't mind smoking hash tasting weed, I prefer not to.

It is absolutely NOT settled science, as a matter of fact as an actual scientist I'd prefer you not use the word science to describe your debunked flushing myth.

Flushing is silly and has zero scientific basis. I'm not going to turn this thread into a debate with you, but I will put real science up against BS stoner lore any day. "Settled science" my ass. Do you have any peer reviewed citations to back that up?

Flushing is a myth that does nothing but starve a plant of vital nutrients when it should be taking in nutes at the peak of ripeness. It's just not scientifically valid, there is no mechanism for flushing and no other agricultural product is flushed.

Tell me, how exactly would you "flush" an outdoor plant grown organically in the ground? Should I flush my tomatoes and peppers and corn too? What about my chickens?

I think flushing is still a hotly contested subject (as seen in this thread :}) and I think partly why is that it isn't black and white.

I often look back at what Lucas (guy who came up w/ Lucas formula) wrote when it comes to hydroponics:

Flushing is recommended only for pots of medium that have accumulated nutes concentrations above 2000 ppm.. That does not happen in ebb flow at 1100 ppm..

Flushing is needed when someone is growing in a dense medium, like soil, coco, peat mixes, etc. These mediums, if watered with nutes at 1100ppm every time, will accumulate too high a ppm.. but that is depending on how often they are watered, how often they are fed, how much they dry out between waterings, etc..

But none of those problems apply to an ebb flow with GH at 8ml micro, 16ml bloom per gallon

If you want to smoke harsh, poor burning weed, have at it. But peddling half truths and false claims to others is not helping them. I'll stick with what the nutrient experts say, backed by their R&D. Plus, I could care less what you think about my calling it settled science. From all I've seen and read, it is settled. I'd prefer you not give others misleading information.

There is a long thread about this....with some great references. My be useful for the original poster to decide on which side of this particular fence they would like to be. For what its worth....I don't flush either. Meds burn great, end up with nice white ash. In my opinion, good burning meds probably has more to do with a proper cure than anything else....just my two cents, though. Hope it helps. Have a great day:pass:

I was going to pull up pop22's thread to post here, great info to read through.

I used to flush, only do more of a "cleanse" now where I feed light but keep up with the organic teas, humic & fulvic acid and other vitamins right to the end.
The thing that got me thinking the most about this is a few strains I have grown state that they put the most weight on in the last two or so weeks of flowering. I thought it was a terrible time to starve my plants when they need food the most? Confusing. But there is no difference in the bud from when I used to flush to now, so I just keep doing what I'm doing.

A proper dry and cure is where it is at. My stuff is smooth and tastes great; haven't had one complaint from anyone about it.

Not here to change anyone's minds, but it's good to look into both sides of this hotly debated topic. Arm yourselves with knowledge from both and decide on your own.

Myth or not-science or not- makes no difference in a soil grow.
I switch to water at the first amber trichome and harvest when ready.
Curing has the most profound effect on the final quality.
