Flushing before harvest

afew of my plants are flowering right now in 20 gallon pots and my plan for flushing when harvest time comes around is to do just a partial flush, 20-30 gallons per plant. I’ve red a lot about wether or not to flush and I think doing a partial flush would be fine for me, should I do the flush 3 weeks before harvest instead of 2 since the nutrients won’t be as leeched out as they would be if I used 60 gallons per pot? What do you guys think of this idea, will I have harsh smoke? Planning on using big bloom, tiger bloom, and bembe sweet and dandé during flower, I only ever use 1/2 strength per gallon never full dosage.

Tapering/slowing down your nutrients towards the end of flower will be a lot more forgiving to your harvest rather than overwatering the root system, which can slow down those last few weeks especially if you already got root problems.

Fwiw, some people refer to flushing as tapering down or using water only towards the end and others think its pouring 5x the pot volume one time to get rid of "nutes" stored in flower. They both do different things so when somebody tells you to flush, it doesn't always mean to overwater your roots to death.

In soil with balanced ratios and no excess, pouring 5x the pot volume doesn't make any sense and is bad for your roots and humidity levels which is still important in those last few weeks.

Honestly though, it is your grow and you are free to try both, just pay extra attention on how to dry.
 
Everest Fernandez has a channel on youtube called Just 4 Growers. There's a vid about flushing. You should watch it. His vids are great, he visits a lot of the LPs in the states and applies what he learns to his peppers. Really helped me start my pepper plants indoors, and when I started growing weed too.
 
A professional grower here flushes by watering with RO water for the last 2 weeks. I’ll promise you his products suck. Tasteless and harsh. The shit is in more than one legal store in the state and every person I know who grows and knows quality agrees. Harsh. Tasteless. So much for the goal of flushing.

THIS IS THE TRUTH!

Look to your leaves to let you know.

Sick, pale, washed out, falling off on their own when it’s not a light penetration issue.

These are all signs your plant need nutrients.

You cannot flush nutes out of a plant. You can only flush nutrients from your growing medium.

Plants transport nutrients as ions.

Chemical nutrients = ions already available for direct uptake by your plants roots.

Organic nutrients = microherd has to convert organic compounds into ions for uptake by the plants roots.

Ions are ions it’s just how they’re acquired that’s different.

No need to “flush” hydro grown either.

Ahhhh just straight water for the last 3 weeks or even 2 weeks and consider it flushed.

Depending upon growing medium being used.

If you are using something like coco it holds very little nutrient reserves unless you’re organic.

Coco after it’s 2nd or 3rd watering of just plain water would be causing rootzone shock and reverse osmosis would be happening in the rootzone. Causing deficiencies in late flower when stacking and swelling should be going on.

In soil using plain water feedings towards the end of flower isn’t as bad, as soil can retain more nutrient content than coco.
But that’s as long as there are organic compounds still present to convert to nutrient ions for the plants.
