Do you mean soil or hydro?

You'll know becauae it will be a day of the week that ends with a Y...... ;). Just kidding.

There was just a thread where there was a study that showed flushing basically doesn't matter. I think it probably comes down to what you like. It seems that if you do want to flush......and we're talking just water only at the end, right?......it shouldn't be for very many days, 14 might be the max, but maybe 5-7 is better. It's probably a good idea if you're using chemical fertilizers but not if You're using all organics. But at least this one study didn't find any improvement.

In soil

Flushing is for toilets sir. Keep that soil alive and happy for its next run.

In soil

Ok, but what do you mean by flushing? What are you using? If you're using chemical fertilizerrs, and you mean water only for the last week, sure. I would do that. If you mean flushing the soil with heavy amounts of water, or starving them of natural fertilizers, that's probably not good. Ultimately you get to do what you like best. Try various strategies and see what you like better. Keep a journal that you can refer to over time so you can track what you do.

That makes since it's my first grow so I'm just glad they made it out the ground. I plan to do water the last week and doing my best at guessing when that is. Do autos automatically turn yellow as cycle ends?

All plants typically start showing fall colors near the end as they’re using up the nutrients.

If you flush, you take out all nutrients from the soil and they start taking nutrients out of the leaves faster. If you don’t flush, it’ll still happen, but more slowly since there’s still nutrients in the soil.

Flushing removes all nutrients from the soil, so if you do it to finish your plants off, and you do it too soon, you’ll need to add in nutrients or risk a hit in quality or harvest size. If you keep adding nutrients all the way through til the last feeding, you’re likely wasting a week or 2 of nutrients. Not the end of the world, and might be just fine if you’re going to reuse the soil later on. Switching to straight water at this point is fine since there’s still nutrients in the soil for the plant to live on.

There’s only 1 reason to flush: you have some issues going on due to the imbalance of nutrients in your soil, and you want to “start fresh”.

Plants in general.......the leaves will most likely turn yellow as they ripen and near the end of their lives. But not every variety under evety circumstance will. It's like asking if trees turn colors in the fall. Well......most? But not evergreens.

You're not going to do anything wrong if you withold nutrients (feedings) 7 days before you harvest. But only over time and many grows will you determine for yourself what you like.

Something more important is to hone your skills at curing. How you dry and cure, over at least a couple of weeks, preferably more, will have a far greater impact on the quality of your final product than nutrients vs. no nutrients at the end before you harvest.

I think......he's talking about flushing in the sense of water only for the last week, and not flooding the soil and stripping it of all nutrients. If it's just the water only thing, flushing really is a misleading word.

If that’s the case, then yeah, I agree 100%

I don't if he really said yet........hey, I cringe too when I hear the word "flushing". Unless someone has toxic soil and must use it, it's not a good thing to do. :(
