Confused about Flushing plant

Hi guys, so I'm growing a couple a plants first time and I'm a bit unclear about the flush process . Can I simply just run 10-15 gallons of water per plant and assume the ppm will be low enough, or is the ppm meter crucial here ?
2) do you only flush the plant the one time and then wait 10 or so days before harvest , or are you flushing it every day for 10 days and then harvest ? Thanks!

Don’t waste your time worrying about flushing. Just feed until the plant is ready to harvest. If after a few years you want to try flushing you will have a better feel for when the plants are ready. Most new growers that try flushing mess their grows up at the end for no reason. There is no real reason to flush at the end of a grow, it’s more for hydro growers to get salt buildup out of the medium.

Don’t flush at all. It’s bro-science and doesn’t have an effect on end product. But it could have a negative effect if you starve your plants.

Hit the search button in the top right corner and enter the word “flush” and see other threads on rollitup discussing this topic.

Out of curiosity can you show us some pics of your ladies?

Appreciate all the feedback everyone. I like that approach. I was under the impression it would make the bud harsh or give you headaches etc . So I will post pics . I have 3 autoflowers I failed lol . I now know they need alot more light then what I gave them . But my first cbd photoperiod seems to be doing alright. Here are some pics

Total “Bro Science”, they’ve done tests using mass spectrometers to measure the amounts NPK, sugars, etc in plants, flushed and unflushed they found there is no measurable difference between flushed and unflushed, plants and in taste tests most people preferred unflushed plants. Harshness is about curing!

Edit: There is one area where flushing can be necessary, that’s if you’re using synthetic nutes. Synthetic nutes are chelated to a salt (not table salt), the salt drops out in water and releases the nute for the plant, however, the salts can build up in the soil and interfere with nutrient uptake, which necessitates a flush. Water three times the volume of the pot. This is usually done mid-grow, and is only necessary if using synthetic nutes.

yep toilets are for flushing, its a waste of time,cannabiis plants in soil in the wild dont need flushing, so why do it. and there taking nutes up untill harvesting

yeah, going way back in a book i read, there were 2 spikes goimng into the base of the stems of the plants at 90 degree differance to each other
i just found this if it explains it dor you

Wait , now I'm confused . So these are the nutrients I'm using . Would i need to flush the plant ?

I swear by flushing but am willing to give things a try. No flush at all that's new how bout at least lowering ppms going into final weeks before harvest?

I have used those nutrients since 1996 and have never flushed and never had harsh smoke that wasn't in my fucking up a dry/cure sequence. I run a low osmolar solution through my coco every time I mix a new reservoir to rinse out any excess build up for 1 watering. Then resume actual feeding the next and mine are fed twice a day.

Flushing is a method used in hydro to clean your substrate from excess nutrient build up. It's for the substrate only. Plants take nutrients across a semi-permeable membrane. It's essentially a one way street. So nothing comes out of your plant by that method. All flushing a plant does is starve it.
