PH

My question is regarding watering the plants with different PH levels. Let me explain:  Some grows I will use a 5 gallon bucket and set the PH at lets say 6.5 then all the plants get 6.5. Some grows especially with some strains I will water the 6 plants with 4-5 single gallons each gallon varying in PH levels from 6.2-6.8, my question is does the plants react differently if it gets water with 2-3 different PH levels at one time ww know its good each watering to fluctuate the levels so the plant can absorb all minerals needed, can it react to PH fluctuations during the same watering?

    • good question. my res fluctuates all the time.i just make sure it doesn't get to far one way or the other. but i would think it would be fine as long as they are within range.

      • More of a curiosity question on how the plants would react, but I think you and others are right as long as in the range plant will do it’s thing.

      • If your water only fluctuates .5 to .7 on your ph then the soil should not be too far from you centerline.  

         

        Letting it drift at certain points can increase the take up of nutrients to the plant.  Someone put a sweet chart up one time but I forgot to save it....

        • Thanks Sarge, if you run across that chart please post I would be interested in seeing it.

        • in DWC i play it loose with pH. as long as i am in the ballpark i am cool. thats why i say it is good for a lazy person like myself

          Remember that in soil pH is buffered by a few things like dolomite and oyster shells (if you are using Ocean Forest )

          • I have been lazy myself last couple of grows but this run I wanted to feed each plant individually based on what I think they need and was pondering about the PH thanks bud.

          • That's an interesting question, can I ask what you are smoking? Actually I noticed a difference and thats why I started mixing my stuff in a 6 gallon portable washer. Once I started doing that the PH and PPM were the same from top to bottom. I think an auto feed system does the same thing

            • Also unless you water in the same sequence every time I think the law of averages says it will be a fair balance

              • Haha I was sipping on some whiskey and smoking Super Silver Haze, was deep in thought. I agree though just trying to keep in range will give it the fluctuation needed for nutrient uptake. Thanks man.

                  • PH can definitely be experimented with. TBS... I loved Sub and CPW's take on this subject ! I've grown a shitload strains maybe 200 plus, and honestly I never really tried to match a strain to a certain PH . I would tend to think that Cannabis needs it's PH to be within a certain range, and not that specific, to where it would matter. That is just my opinion . I almost forgot, your waters PH is important, but like SUB mentioned, the PH of your substrate is just as or more important. It can be a balancing act between the two.

                    • I came back to read your replies again because I got the one off again and I like what your throwing down about the soil ph and I also believe I have not been drifting it far enough one way or another I could also write down each time exactly what ph I set the last feed at.

                      • depends on what the final ph is...I would think no prob...in dro 5.8 all nutrients are available...

                        • I would imagine doing multiple levels at the same time would average it out. What I do is just get it 5.5-6.2 if it's in between there it's good. ph matters but I have never noticed a difference when keeping it at a specific level. I like to do the method with minimal effort that's how I get the best results is by giving the plants less love lmao. Obviously I do training methods of course but I neglect watering at the beginning on purpose so the roots will spread in search for more water.

                          • Thanks OG and good point maybe overthinking things a bit I try to drift the PH but maybe not enough
