Flushing for 7-10 days

[Mistadobalina]

When flushing a plant for 7-10 days in Reverse Osmosis water (DWC hydro), should I worry about deficiencies appearing/killing portions of the bud? I've never flushed for that long.

p.s. will be using AN Final Phase.

no not really, you will see N deficiency but thats the whole point of flushing, to get rid of the icky chlorophyll and nitrogen

If your plant is healthy she will just gradually and gently start yellowing, but if you start off with deficiencies, yes, everything will get worse.

I always flush my plants but this year i REALLY flushed them , 2-4 weeks only water and then the last week i flushed the soil 3/1 with water. So for a 50 liter pot i flushed it with 150 liters of water.

And let me tell u it didn't make any difference in taste. Furthermore i think they tasted better last year when i just gave them water for 2 weeks in the final phase.

150 liters of water! Good grief!

Insightfull post - I was thinking of doing the same thing - just running on water the last 2 weeks...

hmmm nothings even yellowing!! leaves are turning purple though, is that a sign of nitrogen deficiency? I'm only 2 days into this flush, 8 left hopefully.. i really dont wanna have harsh smokin buds this time around.

my last dwc flush was 10 days
2 days water/flora kleen then 8 water

10 days is nothing. next time im going longer
still too green IMHO

Flushing is a matter of personal taste, seeing as how there is no other plant that is flushed before harvest. The key to remember is that (assuming proper feeding) you are not flushing the plant, you are flushing the media. A longer flush (10-15 days) is necessary for soil, but other media hold less ions. I use hydroton which holds nothing, so I only flush for 2-5 days for a tasty clean burn.

Don't flush for too many days, ur wasting grow time.

Color changes are alright when ripening, think of the trees in the fall. Get to know ur strain for best feeding.

Glad I found this thread as I'm also at the flushing phase.
About a week ago I used Botanicare's Clearex in 5.8 pH water and flushed 2x volume of soilless media.
I have only been giving the girls 5.8 pH water since then as required.
A handheld microscope is used to watch their trichs.
Does this sound like I'm doing this correctly so far or should I be flushing more?

I start to flush when I can see amber trichs, I try to flush for at least 7-10days in soil and 5-7 in dwc. So i think you're good...

one other thing to consider is if you have burned or stressed your plant, at any time but especially during early to mid flower, you may have damaged its vascular system. This impacts its ability to take up water and nutrient and evacuate via transpiration .

I would imagine many folks have damage going in prior to flush that impedes the plants ability to circulate your flush water through tissue.

what do you think the result might be?

most who develop a "lock" on any particular strain can actually "finish" the plant ripening without burn damage (most tissue holding N and chlorophyll flushed) -I have been diggin doobieducks grows lately where it is disgustingly obvious.

I have also seen many arguments about this and have no intention to dissuade any from different techniques or opinions; just registering my own. There are far too many variables for it to be "one-way".

It's trickier if your trying for something short of fully ripe or dealing with a strain that has a medley going on. There is often a thin line when an excessive or ill timed flush will degrade the plant potency or starve the plant to the point of degradation (wherever the feck that is)..

I have had my share of near misses and
Its kinda like learning to golf for the first time and you hit one sweet.
feels good.

leaves turning purple could be plants natural "autumn" colors, or ...duh duh duuuh;
Nitrogen Toxicity
Tips will purple at calyx and leaves if exessive N builds up late in flower.

Newbie here, i was wondering how much runoff should you get for a proper "flush", how many times per day should i flood the medium with RO water?

I have been giving the plants straight RO with like 10% runoff is this enough?

 

[Yes4Prop215]

Any responses?? ALso, when i flush and measure my runoff, its 6.3!!!

Im flushing with 5.8, how do i keep the 6.3 down???

 

[Wat it do]

do you need to keep the PH at 5.8 or do u jus add the clearex?

been lookin for the answer to this question....
i read some threads that vaguely described this and some said to let it be and some said to lower the ph.....



DOES THE WATER NEED TO BE AT A CERTAIN PH?

btw: using clearex in an aeroponic rez/system

 

[DankHawk]

I dont understand why it needs to be PH balanced when there are no nutes in the water for the plant to absorb... wouldnt a ph lockout be better if your trying to get the plant to start using all its own N ? Besides that you wouldnt be locking anything out if there is nothing there...

 

[medicine_man_bc]

in hydro ph 5.5-5.8 coco 6.0 dirt 6.2-6.5. its natural to see deficiencies, the more yellow, the tastier they "should" be.
