Flushing in a bubble bucket.

Hi guys, I was curious to how you guys go about flushing your plants the last two weeks in flower with bubble buckets. Do you just change the water every day with fresh PH water, or do you do it every other day for last two weeks?
Thanks for any help
 
Since youre asking this question I would guide you to keep feeding until they're about done and replace the solution with fresh water for a week. You don't need to do a 2 week flush in hydro. I would do it for a week. So if ur growing a 8 week plant I would start the week flush at wk8.

reason is everyone on this site, including me start counting 12/12 at different times. so whatever the breeder says for flowering should be used as only a guide. Most plants take a little more time than suggested.

The goal is to leach out N from the roots - flush with fresh pH'd water (RO if possible) and check EC. On day 2, if the EC has gone up, flush again. Repeat until you stop seeing notable changes in EC (rising) and then you can leave that water until harvest.
 
I've read lots of convincing information that flushing is not really needed in hydro the same way it is in soil or less so in coco, yes coco is hydro.

If you consider how long it takes to see toxicity or deficiency when growing in soil compared to hydro it seems clear that a shorter 2 to 3 day flush at most is all that is needed.

I tried a 2 week flush and then a 2 day flush and besides the effect it has on foliage I couldn't, either could anyone else, notice a difference.

I am lacking on years of experience with only a couple under my belt but traditional flushing in mediumless systems seems like a total waste of time and perhaps ripening potential.
 
Others might disagree but just keep managing your EC until the end. No need to starve your shit I think. You are not going to suck the nutrients out of the plant somehow. If you have burned your plants or whatever during your grow that is what is going to get you. Not the flush.

The plant does exactly that though. The leaves are energy reserves and they turn yellow during a flush bc the plant is starved in its root zone so it eats away at those stores in a last ditch effort to survive. Some people don’t take this step and their reasons for this vary but there is no ambiguity about what is actually happening to the plant during the flush.
 
If they are dark green I think it's fine to flush them to lighten them up a little. Dark green leaves in the buds freak me out and makes me think it is over-fertilized.

but if you really want to, why not a 4 week flush to really clean them out?

I had a friend tell me this he was dead serious . Told me my bud would have black ash if I dident . People will regurgitate all kinds of silly things .

yep, the white ash vs black ash argument is still alive here too. it pops up every few months. lol.

It doesn't matter what you guys think about flushing. It's a step he wants to know about.

I agree it's not what he asked but it doesn't mean that it's not an important part of the answer he didn't ask.

Flush, sure, 2 weeks, no, 2 days, sure but in the end you should always take what everyone says with a grain of salt and just use it all to make your own decision.
 
With bubble buckets they will lighten up and then turn yellow in just a few days like 3-4 days. It will be obvious once they start turning yellow that the flush is about over. No need to go 2 weeks.

Being an annual, wouldnt it be doing that on its own? You know like its the end of its natural life when the buds are ripe, so it is going to yellow anyway?Just curious.

In nature the buds are developed to be pollinated, not flowered indefinitely for humans to pick and blaze, so I don’t think the process of flushing is even relatable since it’s goal is to make better smoke
 
I've always understood flushing even for harvest has more to do with the soil then the plant. Yes it uses what's in the leafs perhaps but it doesn't take weeks it takes days in hydro.

Yeah, anything hydro you see results the next day. Thats what I love about it.

This is strain dependant. Generally, ive found that if a strain usually finishes in 8 to 9 weeks then the most weight (calyx swell) comes on between wk5 to 7. If your strain finishes in 9 to 10 weeks, then the calyx swell happens wk 6 to 9. Etc. Calyx swell is the best indicator of when a plant will "finish."
