Is flushing based on any science?

I'm on aero. Soil tests don't really matter do they.
I'm talking about what is in the bud. I'm thinking the chemicals aren't in the bud anyway. They're in the water then the roots suck up what they need and the plant takes what it needs.

Plus most people say that if you cure it right it doesn't matter. So where do those alleged nutes go during cure?

Plants dont take up nutrients in the form of salts (thats what i was getting at with @Mad Farmer DeeJ what did you test? ) , if you've overfed then you can only prevent from feeding more which should be blamed on the grower not the flush. Its the chlorophyll that gets left behind. Your flowering/cure skills will determine your products outcome

Would this apply to food crops aswell?

no! I only eat organics and actually want to consume the nutrients left in the food.. kinda a silly question… i grow ganja with organic and non organics depending on the market.. I believe ingesting nutes through smoke is different then ingesting through food as well.

here is some science...
Okay… jeez people are sooooo opinionated.

Ill start with I flush.. I flush for a week before i harvest.. damn near until the plants yellow out.. for me its not a taste or burn ability.. I actually have connection to a soil lab and have ran finished product through a LICO machine. LICO machines basically tell you fertility amounts in soil. (npk readings) I will share the lab report with anyone who PM's me. So i have science to back this.

The lab analysis proves that by NOT flushing our soil the finished products contained high amounts of residual fertility. With one flush 3 days before harvest it lowered by more then 60% and with 3 flushes it lowered it 83%.

Im not saying that this will effect taste. For me its a health thing……. I use organics and chemicals in combo so i NEED clean buds for comfort...

flushing can mean two things as well. there is the finish flush right before harvest (usually 3 times the amount of container size, this is the one I'm referring to above. then there is the normal flush which is way less water.. its not even a "flush" simply a "just plain water water"… and listen its depends on how you fertilize and what you fertilize with… period.. If your a heavy, more is better kinda person you should flush weekly especially if you use a lot of liquid organics ferts.. as for the few people that say they don't flush well i guarantee you feed a whole hell of a lot less and use fewers types of liquid ferts.. I will not argue with anyone this is what i do professionally. All i will say is

YES its based on science. if you know anything about the organic soil matrix you will flush occasionally… If you don't then wtv good for you.. I wouldn't smoke your shit anyways… hehe jk read a book...

I'm confused. You said that you run "finished product" through a machine that is designed to test soil? So you are testing your weed? Also, what is "residual fertility"? What exactly are you measuring? This is the first time I've heard this.

look up what a LICO does.. i testing my weed for residual fertilizers thats it. NOT THC! i wanted to see if flushing your soil is needed or not. I personally think it is.. its the same machine that gives npk results for soils and soil additives. it also read c:n ratios and a whole bunch of other stuff depending on which LICO you have.. The machine cost about 100k new i trust it!

The problem is, your testing soil not weed right?

What does LICO stand for? Not finding anything so far.

So does it test the contents in the plant or in the soil which is it? I didn't know you could directly test NPK in a plant.

Tbh nobody should be feeding to flush weekly, the plant would grow half as fast as the unflushed properly fed plant which makes no sense considering double the nutrients were used on a smaller plant.

it test the contents of a pant.. and the soil if that want you want to test.. I was testing the flowers in this case.. also your flushing comment, your opinion..

listen all i can say is a when a 100k dollar machine talks I listen.
I place finished dried buds in LICO it said what it said… When you flush, the flowers contain less nitrogen phosphorus and potassium in the finished product. whether it changes in organic grows idk. i only tested for NPK reaing not things like heavy metals we can only get that information from a third party lab as we can't test for heavy metals in our facility.. I would like to run this test someday though… if only third party labs would test my buds :P

no dude.. i tested the flowers… have you guys never heard of a leaf tissue sample being tested for nutrative quantities? I do it everyday on tomato plants and other things…Its how we compare nutritional uptake between our soil trials.. honestly its how we build our soil recipes..

Clean burning buds aren't a sign the fertilizer is all gone… not always at least.. from what i got from these test properly dried and cured buds with high amount of fert still burn clean and white. I did still end up smoking the product that wasn't flushed it was smooth as hell just as smooth as the other two i tested.. its a matter of, now i know whats in my buds….

Here is an example… take Alfalfa. Its is a good fertilizer addition. its completely dried out and cured before selling. But the NPK and micros are still very present or it wouldn't make a good soil amendment. does that make sense? If they were to flush the soil before they harvested the alfalfa depending on when they flushed and how often the finished product after being dried and cured will be less nutritional as a soil additive. please tell me this makes sense

No need to be a dick, not all marijuana is consumed in the same manner is it? Have you never heard of vaporizing or edibles? Get off your high horse dude.

Actually, that was a known fact but take it as an opinion if you wish. Its all good though, btw I've pmed you for that data sheet you claim please. I would like to see if i can understand what you are telling me for the better of the conversation.

off my high horse… lol Im sharing information i gathered on my own time.. in a facility that cost over 2.5 million dollars. I thought i was being nice sharing this information… i guess I'm just riding my high horse though...

I reread my comment.. sorry.. i didn't mean for it to come out that way… I'm not an organic snob i swear :P
it really just came out wrong.. silly as in hehehe
 
I don't think anyone is being a dick.
Let's calm down a bit.
So what @Mad farmer is saying is that he took just buds and tested them at various levels of pre harvest flushing.

Sounds like science to me. Why can't we find this anywhere. Seems simple enough. Seems that all the legal growing industry would figure this out right away.

So you're testing the actual bud?

Why aren't there studies available?

legalities man… its finally legal in oregon. but still illegal to test in labs that aren't certified to do so.. and even then they only test for Psychoactives and terpenes.. I had to sneak it into a lab in a fertilizer facility that had the equipment to analyze this specifically. I put my job on the line someone be appreciative damn…lol... anyways I'm crashing good night my roll it up peoples!
 
I'm not finding anything searching lico. What is lico.
I know the police labs use something like a gas chronometer or some shit that sounds like that......

and they might have.. but the legal industry is not going to share their secrets lol. Me on the other hand i get pure satisfaction out of doing this right here exactly..
 
Plant Analysis Equipment
LECO FP-528 Total Nitrogen Analyzer
This instrument is used to determine Total Nitrogen in plant and other solid materials. It operates on the Dumas method, where the sample is combusted at 850 degrees C in an oxygen rich atmosphere. A 10 mL portion of the combustion gases are scrubbed of water and carbon dioxide and passed through a hot copper column to convert the NOx forms to N2. The resulting nitrogen gas is then measured by thermal conductivity in a helium carrier.

Lachat 8500 Flow Injection Analyzer
This instrument is used to determine (colorimetrically) the concentration of ammonia, nitrate, nitrite, phosphorus, sulfate and chloride in a wide range of plant, soil, water samples and extracts. (ours also measure potassium, its a different model, not sure exactly which one but this should help you..)
