Adjusting ph without overwatering

Take my example here:

  1. Check ph by runoff (which can only be done by watering the plant)
  2. Ph too high or too low so you treat water to resolve
  3. Water yet again? Doesn’t that overwater the plant?

If you keep doing it over an over ya it will

but you wait be fore you try again, but the answer to your question is no, because you wait till the soil is dried out first before you test it,. when done the water will slowly drip out the plant will be fine.



@garrigan62 so it is

  1. Wait for soil to be dry
  2. Water jsust enough to check runoff
  3. Water yet again with ph rectifying water if needed if not just water the second time using regular water

that’s P H water. but if you did the test then there is no need to water for a couple of days.


Here is something you may want to file away.


yes it is important to know your run off ph. there is a reason why your ph is coming out almost a full 1.0 lower than its goin in. soil is too acidic. testing your runoff is just about the easiest way to test your soil ph. but the main question is how do your plants look? are they showing a ph problem? or any problem at all or do they look healthy? dolomite lime is what you should ammend your soil with to bring up the ph. it has a neutral ph. considering its like $10 i believe for a 40lb bag cost isnt an issue and it will last forever. i have ran into same issue with roots organic and after top dressing with the dolomite it eventually climbed its way back up. easiest solution for you tho man, go coco lol. it doesnt have its own ph its neutral like the dolomite meaning the only thing your plant gets is what you feed it and it eliminates the whole soil ph issue. i switched and never looked back…lol
have fun and be safe!

Hey so what I am understanding from this is that if coco is the medium the ph of runoff shouldn’t matter because the coco is always neutral. And so as long as the proper ph’d water is being used there shouldn’t be a ph issue. But that seems to contradict the fact that when feeding the plants there will be residual salts and nutrients from feeding which I would then think would adjust the ph of the fresh water or nutes being added to the plant. Or am I just missing the whole point lol :slight_smile:

What he is saying is the ph of soil would never be an issue if you use coco

Thanks @garrigan62 but now my brain is exploding as I had a plan hmm should I use coco for the last transplant?

Never check my runoff PH unless something looks to be changing with the plants . I know many think that I am nuts but knowing only makes me want to adjust it . If it ain’t broke I leave it alone


It will be an issue if you don’t check the run off once you start using nutrients. Once you add nutrients to your water you need to recheck the ph and for coco that might mean you need to ph up your water. Also get a tds meter then you will know if you are over feeding your girls.

I’ve had really low ph at the root zone but only took me about a week to resolve.

Aim for a ph of approx 5.8 using coco

I’m not sure if this was clarified but the reason we track run off ph ppm is so we can adjust accordingly at the next water cycle. Not immediately unless plant is showing ill signs and ph is toxic levels 4 8 kinda thing
So in other words if your ph at run off is 5.9 and you used 6.5 ph to feed you would water next time with ph of 7 tracking that waterings run off again to see if you are closer to target etc. Since soil degrades and plants feed and change root zone conditions this practice allows you to keep plant in acceptable ranges


@Donaldj thank you for the explanation as those are exactly the details I was looking for!
