I am curently growing in 2 buckets and last 20 days one bucket was 5.6-5.8 and other bucket was 6-6.2 i see no big difference.on 5.6 one single leaf had ph issues but rest is normal
DWC and PH 5.2, 5.5, 5.8 ??

I think of it as finding a point of balance with the uptake. The aim is to utilize a PH that uptakes the nutrients at the desired proportions and rates. If you go 5.2 or so, you'll be getting the wrong distributions.

I try to let mine swing between between 5.5 - 6.
It's beneficial for 2 reasons....
1) The fluctuating ph will allow better nute uptake over time
2) It allows you to balance feeding or just adding fresh water
For example I put too much nute in my water, and my PH dropped down to 5
but my ec was too high also at above 2.1, so now im just feeding fresh water (my water is PH 7.1, EC 0.1).
As the plants drink and feed, the EC will go down and the PH will go up more toward neutral, so once the PH gets above 6, the EC will be low, so then it's time for more fert!
It's kind of a cycle of 'up and down' rather than trying to nail it down to a specific value. The key thing is staying within a sensible range for both EC and PH.

agreed on letting it float in the OK range. but if i had to dial it in on a #, it would be 5.8I try to let mine swing between between 5.5 - 6.

I have a few of those charts, they are all different. BTW, 10 year old thread.

This is something to consider: "Pure water has a pH of 7 and is considered 'neutral' because it has neither acidic nor basic qualities." My water fluctuates from 5.5 to 6.5 and the plants are very healthy.

well yes, some plants, cannabis in particular, prefer a slightly acidic water/soil, AKA a PH of 5.5 -6.
PH 7 is neutral, as in it's not acid, or alkali, it's right in the middle.

Great for plants but very bad quality drinking water for humans, hahah!

i noticed today at the local grocery store they sell alkaline water for drinking with a pH of 9. that end of the spectrum can't be good for long term consumption either i would think?well yes, some plants, cannabis in particular, prefer a slightly acidic water/soil, AKA a PH of 5.5 -6.

That sounds pretty messed up, my understanding is drinking water should be ph 7-7.5.
PH 9 sounds really crazy, I mean why?

i don't know either. i'm guessing it's a health craze or something? sounds horrible to me

I agree!
"When the PH of water becomes greater than 8.5, water taste can become more bitter. This elevated pH can also lead to calcium and magnesium carbonate building up in your pipes. While this higher pH doesn't pose any health risks, it can cause skin to become dry, itchy and irritated."

RE. ph charts and pH — if you check multiple "uptake" charts, many of them look different and that's because they're all pretty much a SWAG. I can't cite the source but one of the on line cannabis business magazines reported a study re. pH ranges and pH charts and the author confirmed that they're illustrative not definitive. In that same article, the author said that the pH ranged significantly across the respondents to their survey of commercial growers and the conclusion was that cannabis will grow well under a wide range of pH values.
I've let pH stay in the 6.0 and 6.1 range when I thought it would help get magnesium to the plants but I have no reason to think that it worked or didn't work - too many variables.
For me, I let it change over the course of the day but will Down it to 5.8 if it's been at 6.x or bump it Up if it's been at 5.7 for a few hours. That works fine because it's a plant and nutrients are taken up over a period of time, ranging from hours to days so it's like nailing jelly to a tree - you can't be sure exactly how things will turn out.

I like keeping my buckets at 5.8 ph. It by the time I change the solution once a week it usually goes up .1 or .2.

It has been said cancer lives in a acidic body.
If it is true ?I do not know .
