Only if you want some mold in your buds. Once you cut your plant you need to immediately start the drying process. Keeping it moist will invite bud rot. Also, there is no way in hell a cut stalk is going to uptake more water than a root system. If you don't want too much chems in your plant then:
1) don't over feed it
2) give it a good bleed off of nutes at the end of it's life instead of a flush
3) or just go organic and forget about it.
A strawberry is an evergreen perennial that produces fruit and lives. A cannabis plant is an annual that puts all of it's energy reserves into one season of breeding before it dies, so yes, the yellowing is actually natural on cannabis.
Apples and oranges people.

Which is why most chem nutes are chemically altered to bypass those natural systems and force feed the plant. This is why they can be burned with bottle nutes but do fine in TLO. The method of uptake you are describing only happens with True Living Organic soil.
No offense, but opinion has no place in a scientific discussion.
No offense taken. As to the "altered" minerals, care to explain? Chelation is the same process microbes use to break the minerals down into their ionic form so that the roots can absorb them. Again. if you read the article. roots are very limited as to what can pass thru into the plant. And an ionic salt of a mineral will have no other compound attached, or it will not pass thru.
The whole idea of the color of your ash has been debunked too, and is not a valid argument. Resin content has more to do with ash color than anything, as well as how fast the cannabis is burned. Get 4 people smoking from a bowl and it will stay hot and burn to ash. A pipe that it lit and goes out several times will have black/dark grey ash because of the partially burned resin..
As to a taste test, when i see one done as a double blind study, I'll believe it otherwise, what people believe is more likely "placebo effect" . The exception to this I would think would be those who are foliar feeding, there lies a path into the plant that bypasses the root system, and is the reason I won't use foliar feeding, at least with non organics.
Lastly, take a look at the MSDS sheets for various commercial nutrients, you might find it very interesting.
As to organics, the only organics I would trust would be those I made myself from my own compost. Even then, I'd refuse to use grass clippings, who knows what the last guy put on the lawn???
