Just found this test done by a Cannabis specific Nutrient company regarding PH.
https://www.rxgreensolutions.com/uploads/6/1/0/9/61090687/ph_clones_website.pdf

Interesting Article, however I disagree with the results.
I have had major lockout issues in CoCo last year when my PH meter died while I was awaiting a new one.
I cant even imagine how not PHing would kill a DWC.

Any input?
Direct input would be; NO such thing as "Cannabis specific nutrients"......
I find RX Green solutions to be an interesting formulation, and yet again - over blown claims and prices!
Their formulations are pretty good in base lines. I find the supplements to be over priced (all of it for that matter) and one seems rather silly as to it's claims.

I would recommend most people (anyone, but especially if you are organic or could cope with switching to organic without personal resistance, although I suppose they make dry synthetics, too) switch to dry nutrients. When you buy liquid, you're paying for mostly water with the nutrition dissolved or suspended in it. Buying dry nutrients, you can mix up your own, or make a tea for the organic crowd, if not just top dress and amend. Don't waste money on water, get a purer form.
If you attempt the raw nutrient thing.....I suggest you check the source chem first.....Some may be better in their use then others. Examples would be like, Avoid Ammonia based N, Ca sources can be great for the plant or good for the plant but, make a better "buffer" then the other Ca source..There are SOOOO many other things to understand about nutrient sourcing......research is important here.....
I always look to the source in synthetics, for a big part of judging it's quality.... And it's effective use purpose.

Understood. If I ever go synthetic, I'll probably use that Jack's Citrus I hear so much about.

Been doing this for years. Started outdoors then moved indoors. I've tried a bunch of different nutes over the years some with shitty results, some with good results. I started with GH then moved to Advanced nutrients, then dyna grow, then Botanicare, Foxfarm and everything in between. Honestly can say that I've seen my most vigorous growth and heaviest yields with Advanced Nutrients and 50% recommended dosage . I've heard this and that about a baby raper owning the company I looked it up and supposedly big mike bought that guy out and he is no longer there. AN is the only lineup I've been able to consistently hover around 1000 grams per 1000 watt light. Strains are passed around back and forth between friends and I've seen the same cuttings grown under the same conditions only difference is the nutrients and the AN buds are always fatter, and more dank. Also have seen it first hand where my stalks were literally twice as thick as a friend's who had same cuttings under same lights I'm same Temps, just different nutes.

Everyone always complains about the price but like I said I run them 50% so they last twice as long. plus no Ph issues.

I first tried advanced probably 10 years ago and did not like them. But now I understand what a plant wants and when to give it to that plant I love their product. not saying other nutrients aren't good. I personally just have best results with Advanced . Also for being shitty they sure do win a bunch of awards and cups.

First off. Wheat isn't MJ! They also have differing pH needs in soil. Wheat needs VERY high N levels. MJ does not. I farm organic wheat, oats, rye and corn. They're all grain plants but, they all run differently!

Secondly. there are guys around here that would say YOUR full of shit and that you need to keep the pH levels in hydro LOW at like 5.5 to 6.0 and quote that same paper your posting here.

Lastly......Do what the fuck you want! I just don't care for your propensity to spout BS and affect new growers with not the best practice......I say your flat out LAZY for NOT adjusting pH PROPERLY. The posting of a soil pH chart and talking about hydro is simply WRONG! BTW, YOU said that a pH of 7 was "best" - your first post - line 4.........

In decades of growing. I can say without ANY doubt! Use the "swing" in pH to get superior, uniform results, faster! pH hydro to 5.8 - 6.2 and a tenth of a point extra in either direction. Will not hurt on the odd occasion.

Not every paper written on growing, applies to every plant.

I use these nutes and never PH. Never seem to have a problem. just feed 50% of the recommended dosage in promixe hp.
Their site says the buffers can take the solution to 5.5 in a few minutes. When I tested runoff it was higher than that but maybe my meter is off. It's a pretty crappy one actually. It's the best brand anyway, they say the number 1 nute company in the world. I've seen independent experiments using AN and several brands like General Hydroponics and the AN got the highest yield of all. So it's pretty simple, just buy the AN nutes. That's my advice. Same price as the other brands so why not? I get great results with it myself.

Sounds insane to many but I've found that not keeping a hard nailed pH is best for my flood n drain style,starting off with a fresh rez the ph will be between 5-6 & I rarely fuck with it,it'll drop down to 4.5 for a day or so & I'll leave it so the nutrients better absorbed at lower pH can be taken in easier by the plants,sure as shit within a day or 2 the pH will be back in range by itself .

The same applies to a higher than recommended pH of say 7.0 where other nutrients are more easily accessed by the plants,I'll let it ride for a day or so & sure as shit the reading on the tri meter will be near the 5.8 baseline again.

If you start out with good water,a properly mixed rez & steady rez temps in the high 60's you can allow the pH to float around quite a bit & your plants will thrive,if you have to constantly adjust pH because it won't correct itself within 48 hours something in the grow is seriously off,like a bad nutrient mix,or rez temps not steady or too high,or the plants have a deficiency & are demanding access to a nutrient best absorbed at out of "normal " range levels.

A quick speculation question,were the independent tests you read about published in " Rosebud " magazine ?

A, BOB - THAT'S a SOIL chart! Not only that but, different plants will "set" the soil to it's pH needs.....as much as it can. Acid loving plants will grow in a normal and even a lower acid soil. They just won't preform as well.

Hydro should be in the 5.8 to 6.2 zone. I would adjust to 5.8 and let her ride up to 6.1/6.2 and readjust back to the 5.8 again.

Different nutrients are "most" available at differing pH values. this is true for soil and hydro!
Soil swings naturally. In hydro, allowing the swing always seemed to give me better uniform results.
Spot on talk,not many speak of plants setting their own prefered pH but it's a fact,all charts are a simple baseline generalization & nothing more,soil type nutrient ratio mix & temps play a big role where the strain likes to be for optimum growth .

The strain will show growers where it wants the pH at,I avoid buffer additives as much as possible in my flood tables & soil mothers .

I don't remember where, long time ago actually. If anyone can find a test that showed another brand produced higher yields I'd be interested in seeing it. They put damn near everything known to man that helps plant growth in there. Other companies just aren't even trying hard enough.

I dont doubt you have good results I was just checking to make sure it wasn't rosebud magazine,I read about a dozen monthly publications before figuring out AN owns Rosebud & uses it as an CNR publication ,kinda like watching what we think is news on CNN & finding out the program was a VNR,hell I'm not sure rosebud is still in print its been so long ago .

The owner, Big Mike, is certainly a profiteer. But although I don't like him, he does apparently pay other people to design his products and it looks like he got his money's worth. There's probably other brands with pH buffers in them. AN works for me though and is always available so I'll probably keep using it. I don't know how well it maintains pH in recirculating systems, like for a week or two, but it's fine for drain to waste pots.

Yup he is and, like I said - it works.....BUT....

All his lab and chemical engineers have either quit or got fired. The head lab man got so mad at the "unethical way the company is run and products represented" that he quit! He started his own nutrient company and the Mike's smoke'in hot girlfriend left with him.
Met them at a well known W Mi growers supply shop and large scale internet supplier of all things growing. I link from that store regularly...
He was quite nice and rather forthcoming about "Big" Mikes business ideals.....your being lied to more then you'll ever know about AN...

Now again, I'll say it works. Rare Dank himself uses, or used it....he gets/got shit for it too.....Don't mean it's the best.
Just how would you judge that? A good grower can make just about any nutrient product look "the best" in side by sides.....If it had anything to do with "RoseBud" mag - it's overblown bullshit/propaganda...

Bob, if it works for YOU? USE it! DO what works for YOU!

I still say it CAN be done better, with less, for less!

Dude I used the garbage for 7 years and would've argued otherwise until I met ray cogo. & who really cares about someone named big Mike. Sounds ghey

I am tired from reading BS on and on. PH is important, especially in hydro. The better you are able to PH the medium right, the better your plants will grow. PH needs to drift in a certain range I allow it to go to a maximum of 6.2 occasionally if i want to encourage calcium uptake, and i tolerate it down to 5.5 if i want to encourage potassium uptake. You need a meter that reads correctly to the 0.1 accuracy. Whoever says that maintaining ph is not all that important in hydro, or if they say they grew a full season with ph7, i challenge them to show us the result of that
