Timing a 7d flush — will it over-ripen if I begin flushing when it's ready for harvest and keep it for 1 more week on flush juice?

Hello mate, I agree with other grower that say is a myth. Your plant has already take the nutrients from the soil so now even if you flush the soil now what you think will happen? Yes you wash the soil but your buds has reach the ripeness storing and metabolizing the past nutrient. Good luck and happy harvest!

flushing is a myth. google it. be smart don't buy into broscience.

flushing would slow ripening, not increase the pace of it. If the plant doesn't have enough building blocks stored in leaves, it'll only have a negative effect. don't fret over this. it does not impact what constitutes a flower in any way. don't overfeed. don't underfeed. it's a simple thing to do. if you really want to do it, it's just a matter of familiarity. you'll get better at knowing when there is ~7 days remaining, give or take. pay attention. take some notes if necessary about state of development. you'll find something to use as a trigger.

It's gonna depend on strain and how far you're pushing them. I've had some strains that never seemed to go amber and I've had some that push amber fast.

Too late once they are ripe for harvest, leaving them another week while you flush will alter the maturity levels beyond what you were expecting. Start a "flush" once the plant has about 95% brown pistils and harvest about 2 weeks later once the plant has about 98-99% brown pistils. This will be when the plant will have 10-30% amber trichomes anyhow. You don't need to drown your plants with gallons of water for a "flush", just stop all fertilizers and nutrients and give just plain water in normal amounts and at normal intervals for the last 10-14 days before the expected harvest date and the plant will flush itself naturally. No need to buy any sort of over priced "flushing" additives/snake oil, plain water will do everything that is required.

It will be close, you might end up with more amber trichomes by the end of your process but that is 1000x better then chemical laced bud. In my opinion id rather have couch lock then chokey unsmokable weed. Watch your trichomes and make your decision. Good luck

The best time to flush your cannabis plant's soil depends on a few things. First, look at the trichomes on your buds. When they start to turn milky or amber, it's usually a good time to start flushing. Second, consider the type of growing medium you're using. Soil takes longer to flush than something like coco coir. To be safe, a week or two before you think you'll harvest is usually a good time to start. You'll want to water your plants with plain pH-balanced water for a while to clear out any excess nutrients.

I usually switch to just water for the last 10 days before I plan to harvest. I use the same amount of water as I had been doing when feeding, no need to go excessive.

Hey there I know things can be overwhelming and hard to decide what todo. Personally when I start to see about 25% of the hairs change on the whole plant that's usually a good indicator that the plant only has 1 to 2 weeks left. I like to stop giving nutrients about that time. Usually after I stop giving nutrients every time inwater after that I give a little extra water to do small flushes. Then when plant looks ready to harvest I will give it a good flush and then I wait till the soilnisnsupwr dry and then I harvest
