In promix 2 weeks /coco can be as little as 4 days I've been told

Zero days of flushing at the end. Nutes are reduced tho.

I flush my outdoor plants when I see the guy down the road flushing his apple trees.

Lol does he use nutrients to boost apple production? Honest question

Not sure but he flushes for at least a week longer than my buddy who flushes his corn! All kidding aside, flushing does very little. I'll run a few waterings at the end with just water but that's only if the ripening isn't done.

I flush twice a day on average, more often if i have a big lunch. jk

I only flush my soil if I feel the end of flower is near and I don't see any fade color, indicating I over ammended.
In late flower I usually water 2 times a week, so i'll just go with straight RO water the last 10 days before harvest. As close to 0ppm as I can get. I usually don't want to get a ton of runoff when I water. But, with a flush, I water roughly twice the normal amount.

I flush between 5 to 7 days then it's lights out for 48 hours, then harvest. The plants tell me how long and how much.

Actually yes. Know anything about actual food crops and farming? We consume lettuce and onions and potatoes. Do any of those get flushed?

Good point, I think the idea of flushing came thru in the early 90's with the arrival of synthetic salt based nutes, and to a lesser extent, commercial hydroponics. Before 1980, you didn't hear about flushing the medium.

Is the plant going to shit? No. The idea of flushing to clear nutes from a plant is retarded. It takes in nutrients and uses them. What flushing does do is start deficiencies. So they’re pulling the mobile nutrients from older leaves. Like these dumb “dark periods” before initiating flower. Damned photosynthesis anyway. Right? They basically start dying. Great start to flower.

There is a difference between flushing and just watering to reduce the nuts level.
So, are you asking to flush on removing build up salt or reducing the levels for a harvest?

 

[GanjaFarmer24]

Instead of flushing, I've even seen growers withhold water for the last week before hanging, they say it starts the drying process, i dunno. And the idea behind the darkness is somebody made a study of how cannabis will build up volatile oils overnight and as soon as the sun comes up/ lights on they start to evaporate, that's why your garden smells best in the morning. I think. There are so many different rabbit holes to go down.

I give water twice before chop and I chop at lights on the day I would water. Why load it with the water we want to dry out? But 2 weeks flushing after his 48 hour dark period and my buddy is always amazed. My buds are bigger and harder. He just doesn’t understand.

It’s because I fed them for the two weeks he’s flushing.

No argument here, so long as you're not driving them to foxtails, there's a happy middle ground for everything.

Foxtail is ugly and hard to trim but harmless. Some strains are more prone to it than others.

I know passions run high with this topic….and all that matters is some good bud at the end of the grow. Personally, I’ll start to flush when I decide to smoke my soil…..but not until then.
If I had to flush, I’d make sure my plants were ripe going in and/or there were plenty of green left for reserves. The last thing u want is to start starving a plant just as the buds are getting ripe and swelling up.
I’d be more inclined to let the buds get ripe…meaning no new pistil production and all hairs have turned color and receded….then give water only for the last watering and flush it with as much as you like. Then you could do the 48hr darkness thing if you prefer.
When it comes right down to it, if your buds are ripe, you can run 3 gallons or 30 gallons through it and call it a day…..neither will do much harm or good.
