flushing question

i have a GH waterfarm and i was wondering if i'd get adverse affects if i didn't pH the water while i flushed. i'm planning on using GH flora kleen as well

so my assumption is no, because there is no uptake of nutrients. yet, i'm just looking for clarification or advice.

in my opinion, the ph doesn't have to perfect for flushing , so I don't adjust unless it's really bad...like 4.5 or 8...then I'll adjust alittle

okay, thanks. i guess i'll have to adjust it still, it's between 8-9 so it's reasonably high

There is no point whatsoever in flushing with ph'd water, as ph up or down are used to help the plant take up nutrients the exact opposite of what you want when flushing.
Straight water that has been standing at room temp will do the job.

right, those were my initial thoughts

I use Final Phase to flush hydro. It is recommended that you use PH of 7.0 during flush. Your plants do uptake the flushing solution to remove the nutrient salts that store in the flowers. Hope this helps

False information as I too use Final Phase during flushing and even Advanced Nutrients tell you not to PH your water during the flush.

thanks fot the info, do you have a source for this?

this the first hydro plant i've grown, and i'm still surprised just how east it's been.
in soil, this strain starts eating itself by now, when i start the flush will it show signs of using it's internal sugars? it's still so green idk

Yes the plants will lighten in colour towards the end of the flush,just make sure you do not chop early make sure that the pistills have receeded and the pods have swollen. http://www.advancednutrients.com/hydroponics/products/final_phase/final_phase_product_information.php

i personally think if you flush with a high ph water then it will raise your new water change ph

Fenderman - I do not give false info. True, Advanced has recently changed the Final Phase label but if you go here http://www.gchydro.com/prd/PHA/Advanced_Nutrients/labels/finalphase_label.jpg you will see the old label. It clearly says Rockwool and soil - use with properly PH balanced water and Final cycle - ph should be adjusted between 5.2-5.8 for hydro and between 6.2-6.5 for soil. The only false info was the ph level which I misremembered. This is forgivable as my water is naturally 5.5 ph, so I no longer worry during flush.
