question about ph...

[zukinjo]

Ive done all my grows in soil to right about now...i bought bluemats to start my first coco grow...starting next month...

When i mix up my fertelizer and water i add ph down to about 6.5 in flowering...and last time i didnt use all my fertelizer (about 3 days after) i checked the ph again and it was about 7.5...and i know thats normal...but can anybody explain why that happens?

I am worried when i will do my coco grow the ph of my solution in the
reservoir will be 5.8-6.0 and whit time the ph will go up to much and the plants wont like it?

Am i whey off or is there something i dont know?
And guys keep up the good with work helping guys like me...
peace....

It starts with your source water and its alkalinity. If you start with RO water then the pH won't bounce quite like that until/unless your plants begin using up nutrients.

its actually a pretty complex question. i would suggest you read this:https://www.icmag.com/ic/showthread.php?t=23357

Yep, alkalinity of the water source. Doesn't matter what pH you're giving your plants, the buffers are there and they're going to affect your medium the same way after a while.
As SM said, RO would resolve your issues but short of that I'm out of suggestions. I lost that battle long ago with my water.
BTW just read the link.. never tried the hardwater nutes but I was under the impression that they just had less cal and mag. I am not confident that they'd actually combat the buffers in your water effectively.

So is it a major problem if my ph swings in 4 days from 5.8 to 7.5 for my plants will the roots sufer? i want to use bluemats does that change anything?

Started to read the thread you gave me...tnx cravin

And what are your solutions for ph stability?
Do u use RO water or 50/50 with tap?i want to use canna coco nutes?
is it good for hard water?

You want your PH to only fluctuate between 5.8-6.3. What nutes are you using? Are you using an airstone in the rez?? Airstones will evaporate potassium(I believe someone correct me if im wrong) causing the ph to rise. I noticed this big time when I first started using a drip setup. Now I use a Dead/Still Rez No airstone all Chem Ferts. My PH stays stable for the 4-7 days my rez stays full.

Make sure you don't use any type of organic based live nutrients or your rez will not sit for longer than 2 days without breaking down.

I had to cut out a lot of different organic nutes and now i use the following.

H&G Coco A/B (Base)
Multizen (Enzymes)
Top Booster (Bloom Booster)
Mad Farmer Moab (Late Flower Swell / Speeds up flowering 1st week)
Rock Resinator (Makes Bud turn to glass)
AN Bud Candy (Only Carb/amino supp that doesn't turn my rez into a sulfur bomb)
Great White Shark (Myco)

And what are your solutions for ph stability?

i run bio-buckets with tap water on a float valve. the beneficial bacterium keep my ph real stable. i add my nutes to my desired strength, then i walk away. if your interested in growing hydro almost set it and forget it style, check this out:

you can see my build of a bio-bucket system in my albums, bio-bucket tent. i've run many types of systems over 20 years, both indoor and outdoor, but i think i've found my holy grail system.

you do realize you've still got a metric shit ton of organics in there, don't you?

 

[zukinjo]

I decided to use cana coco A+B ,Hesi Vit ad Hesi root coplex...
I want to do coco DTW system with bluemats...and vertical position of light to get the max of my growbox as i can...

I dont have a clue how to get ph stabilit in my rezervoar...
So the best thing i can do is to have a small rezevoar?maybe?

guys i found what i was looking for...

that was well worth the read = canna ph.

AN used to be molasses based, but not anymore.

Multizen is vitamins and enzymes derived from organic matter yes but its not a "Live Bottle" Its a hygrozyme / cannazyme replacement all 3 are ok to be used in a sterile rezs.
" there is no longer a need to introduce or create crop vulnerability by introducing a foreign germ culture to your sterile growing environment."

Great White Shark (Myco) lies dormant until it comes in contact with roots.

I used to use Floralious plus (molasses based) and it would turn my entire rez into a slimy sulfur bumb.


The point is if you don't want your ph to rise. Use stable non bacteria nutrients in a still rez.

you realize that you've just contradicted yourself royally.

i don't think that word organic means what you think it means amigo.
and what planet do you live on where you can hydrate and feed live bacterial and fungal cultures (i.e. great white) but they somehow aren't active and alive (read: capable of going anaerobic) until they reach the roots of your plants? in a word you are wrong.

one could overlook some simpleton on the internet pontificating about things they are clearly ill-informed, but to start handing out K- and throwing slurs at me for civilly pointing out the bad information you proffered? that's pretty damn childish. in addition to being an idiot, you sir are an unmitigated asshole.

BigTokes thread, which was linked by cravin is fantastic! Check it out original poster! Thanks for linking the Canna pH site, reading it now and I think it's great! K+

Much love!!!

Dude says he doesn't use organics in his rez, but that he does use plant based ingredients, live microbial cultures, etc. Last time I checked, that was the very definition of organic. And with regard to the bud candy, how anyone could imagine sugars and aminos to be anything other than organic boggles my mind.

It's a lot like saying that you are a vegetarian but you subsist entirely on beef, pork, and chicken. Pretty funny stuff actually.

guys dont fight...

It's a lot like saying that you are a man who likes to fuck other men, but that you're not queer. Pretty funny stuff actually.

If he's talking about the legal definition of organic (and much of how it's defined is a legal issue), then I am in agreement. It's just like the difference between scientific nomenclature and definitions and the layperson's and the word "theory" is a perfect example of that. To a scientist, "theory" means it's been proven. To the layperson it usually means that it's just an idea and has not been proven. EG; the oft used refrain, "If evolution were proven then why is it a theory?"

or·gan·ic adj.

1. Of, relating to, or derived from living matter cultures and plant derivatives. check. the most and probably only relevant definition for our purposes.

2. Of, relating to, or denoting compounds containing carbon (other than simple binary compounds and salts) and chiefly or ultimately of biological origin. ...follows necessarily from 1.

3. (of food or farming methods) Produced or involving production without the use of chemical fertilizers, pesticides, or other artificial agents. well, not exactly, but then this isn't the definition that pertains to what we're talking about. anyway i'm pretty sure the usda, omri, and oregon tilthe don't certify what we do. not yet at least.




not trying to break balls so much, but the level of imprecision folks are absolutely willing to tolerate on these forums is pretty alarming.
and you don't even want my thoughts on folks who are brazen and cocksure as they spout off information that's just plain wrong, as if a cabinet in their dorm room or their mom's basement makes them some sort of authority.

You're totally right Organic was a bad choice of words. I should of said bacteria... Can we get back on topic now?


Run a bacteria less /still /dead rez and you should be a ok...
