How long to maintenance flush ?

Hi !
Everything is going good so far in my DWC grow.
Except in the last few days , My PPM is rising ,the water level is dropping and the PH is dropping .
On a chart I have they say to lower the PPM to correct . I did that 4 days in a row by adding plain water once and 1/2 strength mix ,and the results are the same ... I started the week with 1000 PPM , now it's at 700 PPM .
I would like to Rinse or flush before I do the next mix ,but I don't know how long I should do it .
I have FloraKleen . They say on the bottle to recirculate the flush solution for one to two hours .
I'm in DWC ,is two hours enough ? Can anyone confirm this , how do you do a " between the nute change flush"
When I do a research ,all i come up with is about final flush ...
Thanks for helping !

I never flushed in DWC. I wouldn't use floraklean until the final myself. I honestly would just use water and ditch it all together.

What your experiencing sounds normal. What week flower are you on? How big a DWC bucket?
They will start sucking up nutes and water faster as they get into flower. I would just keep adjusting the ph and ppm as you have been; by adding either nutes or plain water to keep the ppm in line, then ph adjust.

Unless you have excess of salt build up and are seeing problems with growth there should be no need to flush.

If you must flush, just use plain water for 24 hours then move back to your nutes.

I'm at the end of week 3 of flowering ,the plants look very good ,no signs of burn or anything bad ,the leaves are beautiful no yellow tips . They drink a gallon a day in 5 gal. buckets ,and I see them progress every day .
I keep the PH at 5.8 5.9 .
When you say keep the PPM in line ,what do you meen ? I add one gal of 1/2 nutes everyday ,each time it lowers the PPM , is that ok or should I add full strength mix so it doesn't go down ?

Thank you for helping me Mr.Goodtimes !

Full streangth so the pph stays the same.

Also 1000ppm is a little high for 3 weeks into flower. Right now I'm 2 week from harvest and still at 700ppm. I won't give them more unless I see deficiencies. Less is more sometimes. To 'final flush' I cut my nutes down to 250-300ppm for the final week before harvest.

Food for thought

There's no point to flushing in DWC. Just change the nutrients when they need to be changed.

Thanks again ! Beautiful plants , congrats !

Yeah no need to flush.

Basically fill res full of nute mixed water, let res get drunk empty(just above air stones if using), refill res with nute mixed water and repeat.

I used to run like that. My yields and quality improved once i started keeping my res levels consistent through the grow, only letting them drop the last week or so.
