Flushing help please! Do I water as normal or flood the pot? Been flushing for 1 week so far planning to harvest in 5 days.

Depends on your run off EC and colour of the run off . I water or flood until the run off is down to 0.1 and the water that comes out is nearly clear. It takes 3 days for water to fully circulate around the plant so keep that in mind. I've just given a last flush now and will let it dry out then chop. (I'm at the same stage as you )

Because Flushing is a myth... Why is the foliage still healthy? Because of excess in the medium yes but also excess in the plant itself.... Use less nutrients and grow bigger and fatter plants.. It's weird but far too many people are using too much these days. Shades of green.. There is like 1000 shades of green between Yellow and Too much(nitrogen Toxicity). It's far better if you understand that you can not flush excess anything without affecting the plants metabolic functions. And Your far better off to have balance throughout the whole cycle with a taper(or decrease) in your nutrients. Less is more :).

Some growers do either. It depends on what type of nutrients you use and how much and how often. With organics and dry ammendments a flush isn't entirely necessary and just plain water will do unless you've noticed an excess of some sort. Watering to have excess run off is advice dog using chemical nutes and heavy feeding but, remove the excess run off and pour it away, you can also check the ppm of the run off to tell you how much salts are in the medium. 🌱👍

Don’t let water in the tray to not have no drawbacks with mold

First time u flush u will give a lot of water to flush out the residual salt, and that the time u use an eventual flush product if u have it. Then u continue whit a normal watering routine watering , giving water when the pot is light ✌️🏽 Hope to be useful and comprensive
