When to start flushing before harvest?

I would not recommend "flushing" with large amounts of water the last two weeks, it accomplishes nothing and basically starves the plant. If you want to stop fertilizing a couple weeks before harvest, that's your choice, but why would you want to starve the plant as it's trying to bulk up the buds? As for the "chemical" taste of unflushed synthetic nute plants, that's Broscience. There is absolutely no difference in the nutrients absorbed by the plants from an organic or synthetic grow. The synthetic nutes are bonded to a a salt (not table salt) when mixed with water the nutes dissosociate from the salt and are immediately available to the plant, the remaining "salt" is not absobed by the plant. In an organic grow microbes are responsible for breaking the compounds down into forms usable by the plant, but it's the same nutrients the plant takes up. There have been tests of plants that were flushed vs unflushed and the only diffence is a slight decrease in the amount of iron in a flushed plant. In blind taste tests unflushed buds were preferred.

Hi, everyone.
I read that i should flush the plants 2 weeks before harvesting but how do i know when they have 2 weeks left so i can start giving only water? They are in 3rd week of flowering.

The ends are a bit burned so i put the light higher and i decreased intensity from 100% to 75%. Hopefully it helps.
Are they looking okay, overall? I defoliated them for 3rd time a few days ago. I think was my final defoliation.

Don't believe everything you read😉

Thank you. Next time ill try your method, it sounds much easier and not so time consuming and most importantly - healthier and organic.

You're welcome. Using dry organic nutrients does make growing easier. I tend to think the quality is better, too. Note that I usually add some nutrients to the water near the end, such as potassium silicate, Epsom salt (magnesium sulfate) and molasses.

They say not to flush because you don't need so and it does hurt the plant. At the same time if you ever smoked non flushed herb in the first few weeks of drying it will taste like shit longer than flushed herb. Flush earlier if your plant is real green and healthy, and shorter flush for when your plants are yellowing earlier than expected.

People need to understand that this varies by what kind of good ow you have. Hydro, soil with hydro, soil with dry amendments, organic living organic. Every way is a bit different. I choose to grow living organic. I chose this way because I was tired of flushing.

Broscience, see post #21. Any plant that has not been properly dried and cured tastes bad. Flushing is for toilets.

The only caveat is that sometimes when using synthetic nutes in soil or coco there can be a build-up of the salts from the chelated nutes, and that can interfere with the uptake of nutes. This normally happens when you don't water to runoff and occurs about the time yout flip. To remove the salts you need to dump 3x the volume of the pot in water, through the soil, that will wash out the accumulated salts, but then you must go back to feeding because it also washes out all the nutrients.

the difference imo is unflushed herb you get a harsher choke say a week after you bag it. the flushed one would smoke smoother by this time already. just try it yourself, instead of saying bro science.

I personally have done the side by side and have not found any difference and I use to flush for a few days. No more.

Fertilized all the soil plants and didn't even take pictures. I'll get back up there this afternoon😉

I haven’t flushed a plant in years bro, and I have done a couple of tests, take 5 of one strain and flush, and keep 5 and not flush.’the difference at the end of the day was less weight. And some flavor and finishes in the Tl terp dept that def suffered from a flush.
