Pulling salts from the substrate; lowered Cal/Mag requirements due to lowered production of chlorophyll (I don't notice my plants shooting out tons of new leaves toward the end of flowering.); pulling salts that have been previously caking on your airstones; using tap instead of RO water; the list goes on, I'm sure. That's just the things I can think of that would jump my PPM as minorly as 15ppm a day on average, off of the top of my head. 100ppm isn't much when you consider the difference between tap and RO water alone. I'm by no means a "genius", but that's what occurs to me.
Well, 650-500=150ppm. Assuming your plant was using nothing in your water at the time, yet drank 4.5gal of 150ppm water; yes, totally possible. 150*4.5=675ppm. In theory, if your plant consumed nothing from the 4.5gal of 150ppm tap water (Other than the water, of course.), your water should show an increase of, roughly, 217ppm (675/3.1~217.7ppm). Assuming my math is solid (Feel free to tear it up, I may have missed something obvious.), you're left with ~67.7ppm of wiggle room for various factors before your plants starting to dump nutrients back into the solution even becomes reasonable. Assuming the substrate and airstones are going to leach off some salts too, I don't think this tells us much without more controls. Honestly, there's just too many variables.
That's the problem, it doesn't prove anything due to lack of controls. While your PPMs go nowhere, that tells me nothing on its own. Your plant could be pulling nutrients that are leeching from your various pourous surfaces (Unless you cleaned them to like-new condition at the same time you flushed.); meaning your plant could very well be feeding. It could also simply mean that there's nothing in the water that the plant needed; which doesn't immediately mean the plant doesn't need anything, just that it didn't have anything it needed available. Maybe it pulled some things it needed, and dumped some others back out. It's too uncontrolled: You can't account for the makeup or origins of those salts in your water, so you can't definitively say what exactly happened. See what I mean about the too many variables? That's the purpose of solid science; to control as many variables as possible to reduce the margin of error in your experiment.The question im trying to figure the answer out to at the end of the day is. Whats the harm in just feeding straight 150 ppm tap water at the end if the plant isnt eating any of the food out of it anyway? Theres a pile of guys on this thread that claim that flushing is the worst thing evaaar. Youll loose potential they say. Well this pretty much proves that wrong. And i dont rip people apart for chatting with me, not my style, thanxs is more my style
Despite your ignorance of how the plant yields chlorophyll. That's great. Flushing is a fool's errand and there appears to be ample supplies present. Please - post at least an illustration indicating the location of the anus on a plant where it will shit these byproducts.
It indicates the plant is finished. It will grow no more and needs no more nutes. Lower your PPM to 400-600 at the highest. I run mine as low as 250 to finish. However, note there are still nutes! Flushing works for toilets, not for plants. You are not "flushing" a plant by denying it nutrition, you are starving it.
Well i did do a good cleaning of my bucket when i changed the rez, i always do. As for the comment on the plant dumping, i think your right, at 1.8 litres of water a day for ten days at the end of life its obvious the plant was healthy and circulating water well until the end. So since the ppm went up and the water being added was only at 150 there was definatly some dumping from somthing, i dont really by into the idea salts leached from somewhere else. They came out of the plant, which is what i was going for in the first place. Success
Dude its called morals and integrity. I will not buy or sell garbage pot for the sake of a couple dollars. I would never sell uncured bud because the people I know can tell the difference. I dont deal with kids that are happy just to find some pot.
What substrate do you grow in? What kind of airstones do you use? Why is it not reasonable for them to be retaining nutrient salts from your water? For the record, just because you "don't buy into something" does not effect it's validity; if that were the criteria for empiricism, evolution wouldn't be a theory. If you wish to disregard something reasonable, you have to pose some evidence to support your disregard; assuming you wish your argument to be taken seriously.Well i did do a good cleaning of my bucket when i changed the rez, i always do.

I grow in dwc buckets with hydroton. They arent recirculating so theres really no where that salts can build up. My hydroton doesnt touch the water and i use the grey two inch air stones. I know i need a good squirt to raise that much water 150 ppm and i cant see how it would come from residue on the stone. Is that evidence? There have been others that have seen a jump in ppm after flushing, i dont think im the only one, after all theres mobil elements that circulate through the plant right? Why isnt it possible that some came out?
