When to start flush in soil medium?

Man that depends on the strain and conditions...if you are already 50% cloudy it won't be to long...week...two tops I would say
 
Thanks dude, that's good news, strain is unknown so going to keep a close eye on them, they are under 675w of cfl, temp tops at 80 in day, bottoms at 70 in night, rh is unknown but not excessive, soil and 16Litre smart pots, 2 fans in 80x80x160cm tent, canna terra Flores, cannazym, canna boost, pk 13/14, just f.y.i
 
Gotta agree with King here. I don't think they need any nutrients at all in the last couple weeks. This is where defoliating may come into play since the plant has no reserves to draw from.

Interesting to see different perspectives on this. My first DWC grow, I tried to get the leaves to yellow, I kept flushing with plain water but the leaves still stayed green. 2 weeks later, I harvested and they looked as green as they did prior to flushing.
 
Idunno about this. I consider flushing an attempt to remove the nutrients in the media/reservoir.

Nomenclature can make things confusing...
 
Flushing is definitely a controversial topic. People seem to be all for it or completely against it.

I've tried herb that didn't get flushed. It burned white, no cracking and popping and tasted/felt great. This was with salt based nutrients too (GH).

I prefer to flush though mostly because I don't think the plant really needs much in the last couple of weeks, so it can't hurt. Nebula has tested this herself and found the flushed buds to be smoother. It's all anecdotal and subjective, but Nebula's got my trust....
 
That's what I thought but I haven't gone wrong with green75's advice before.........controversial is right!!!!:)
 
C'mon..all good weed taste good unless Fucked up.

Nutes are not the cause of harshness...the salt is

Not all nutes have same level of salt either....

Nutes get transformed into sugar on entry of plant uptake...
 
Dude it's your simplistic, dead pan delivery that makes a good argument, this is just a plant, albeit an exceptional one, it follows simple rules........I don't know........am I starving the plant when it needs it most or am I rinsing out leftovers for bud smoothness........KABOOM!!!!!
 
In a natural configuration (organic or in the wild), it is my understanding that the plant provides the sugars, called exudates to the soil microbes which in turn provide the plant with nutrients. It's the symbiotic relationship of all plants and microbes.

When using synthetic nutrients, they use chelates to drive the nutrition into the plant since they're not bio available.

This, along with the fact that organic is cleaner (no heavy metals) is why I switched to organic... for now....

Greenie, I still love you.
 
Dude I have grown truck loads of weed...Fucked up so many times on this and that and timing for sure...I know all about outcomes from different ways/ methods....still learning

By no means do I think I speak law....I just speak from experience... And from my experience I get Fuckin dank huge buds. I happen to enjoy dank huge buds...lol
 
I'm not debating that. Just correcting your sugar statement...

You still haven't grown organic yet, though? I'll make a believer out of you, one day.
 
"One of the primary examples of this is their ability to send out sugars. Plants secrete an incredibly wide variety of sugars through their roots. These sugars are known as exudates. Exudates are used to attract sweet-loving microbes to the plant roots. These microbes then provide the plant with the nutrients that it needs to grow and survive."
 
Depends on what I am working with during each grow!

Little to no nutrients added-No flush at all. (organic grow)
Nutrients "as needed" then just water with pHed water for the last 10 days.(assisted to organic grow)
Nutrients used through out the grow- then yes- flush with 2 times the amount of water, then continue with light to no nutrients. (synthetic nutrient based grow)
