PH Swings in DWC? I Don’t Adjust My PH

I read about this..the fluctuation is actually good for the plants. As you know, certain elements are able to be absorbed by the plant at different ph levels. The flux allows your plants to get the full spectrum available to it. 5.8 is just the level where most elemental absorption happens. Great video as always Dusa. Edit: if I had watched the video all the way through...Dusa states this ✊🏼

I run a four plant x 13 gallon + 5th 13 gallon bucket reservoir - PA Hydro. The first three weeks of veg show the pH always creeping high. I chase it twice per week. Then during the fourth week the pH drops below 5.0 and I chase that twice per week. Meanwhile, plants look superb. Last couple of grows I ignored the pH and things turned out fine. Lesson: don't fixate on the numbers - watch the ladies.

The water here will jump from 5.8-6 to way out of range. Up as high as 8. Not sure this would work in our area with tap water.

My yields have tripled since i started to pH. So long as it is in a range that's one thing. Advising not to pH is not very good advice since you have no idea where someone's pH was to start with.

I start with 5.5 and let it rise to 6.8. While keeping an eye on 6.8 because the plant won’t absorb if ph is to high so when that happens I re-adjust to 5.5 but advanced nutrients doesn’t require constant ph adjustment

I use pool ph up and down for my outside vegetable garden. Never had any problems saves so much money. $10 for a bag I have used one bag for two seasons and I still have plenty.

Thanks Dusa. Simpler has been better for me this current run. I’ll continue to simplify.

Makes sense. When I feed with coco, I alternate Ph every feeding. Feed at 5.8, 6.0, 6.2, and repeat. And I rarely have to go above 500 PPM in DWC since its efficient and nutrients are easily available.

pH swing is only a problem if youre running low PPMs , only every have issues with iron def with high pH with vegging plants with low ppm , in flower im no longer bothering to check flower pH

was chasing it at the begining as wasnt sure how any of it worked,,,but yeah soon got on top of things and had stable tap water which helped,,,,,but would keep at 6,,,and if it went over 6.4 would bring back down,,,but by the end it worked out the ph would rise slightly,,,the would feed,,,,which would bring it back into range,,,,,only needed the ph down at res change overs,,,then plant and feeds kept ph stable without using any ph up or down inbetween only on res change over,,,but just ran into to some early root root so think i got it early,,,,brought out the H202 worked great last time,,,we will see how it goes,,,,but was looking great till now lol,,,,running a Bruce Banner f3 this time round

Love the video, and some great information about pH, I use Advance Nutrients PH Perfect, not had one issue, Thank you for all the information you provided to everyone, lots of RESPECT FROM THE UK 🇬🇧

Pretty much bud. I gave up after everything I did caused my PH to swing. I now only really worry about temp and ppm

Love the video never done DWC I do soil all the time all organic never really worried about the pH is low as it was between 5.8 and 6.8 I was good And whatever works for you might not work for somebody else . Right on ❤😎

Well my tap water is very alkaline, it sits on 8.0 pH. I guess most of you are using RO water which would explain why your pH swings are still within the safe range, but I have to use pH down to keep it in the 5.5 - 6.5.

Didn’t work out for me!! Commented before I watched i understand what you mean 😊

fuck it, ill try it next run. not having to deal with ph would be worth the risk.

C02 injection can also make even bigger swings with PH. Most people with planted aquariums would already know PH drops at night in general and when you add C02 injection that PH drop is even larger so id expect DWC would be the same. Between my Aquariums, Aquaponics and Hydroponics systems I only change the PH of what I'm adding to the existing mix or fresh fill's ;) Morning reading of 5.9 would swing to around 6.2 by late afternoon with a low of 5.6 lights out (NO C02 injection) expect more change with tank C02 ;).. Never used the trash c02 bags so unsure if they would effect much compared to regulated tank injection which does more the more C02 gets into the water from gas exchange during water agitation. Added edit = info on high tech planet Aquariums can show you so much about water and what PH changes to expect with x=amount C02. Once you get your head around it you can closely predict the change via amount of C02 in the water column.

If you pH it to 5.8 after adding your nutrients it should be good for a week. May have to top off with 5.8 water during the week but otherwise that's exactly what I do and I've never had problems.

I don't really ph unless it's a seedling, after they start growing I leave it be and just occasionally monitor it, never really made a difference, had some yellowing, my ro water is at 6 out the sink, I don't even measure my nutes and Calmag, just feed some tablespoons every water change, managed a qp my first auto grow off one plant, it's not as serious as people make it out to be, you end up just stressing yourself out spending hours watching leaves grow. Eventually you grow extremely tired of trying to chase perfect. People say dwc is hard, it's not it's very very easy, soil is what is hard, you legit have to be there nursing it everyday if not it dies, I've left my dwc for a week, came back it grew and was normal with nothing wrong.. do that with soil and you come back to a dried out plant if your using high temp lights.

Agree with you 100%, But you must control pH level when plant is small and have smalls roots because easy to get chlorosis problem, and block nutrition, leafs start be brown -yellow colors, and plant can die. I almost lost 2 plants in dwc from chlorosis, but quickly change to pot with coco and they alive 😊
