Coco and ph levels

Exactly.

OP states he wants to optimize his feedings but doesn’t really want to. Optimizing coco to it’s fullest potential is achieved through multiple small fertigation events throughout the day.

I guess the OP wants to optimize his feedings in coco while treating it like soil.

even if you monitored your pH in your coco, the results wouldn't be the same for the OP. i would guess a soil pH monitor buried in his coco would get him started to what it was doing?

I mean I guess interest in the pH is good for curiosity sake?
I just think he’d be better off learning how to actually optimize coco.

No sense for multiple waterings/day, if you are handwatering. Multiple feeds/day is not the only way. Or the "best" way. Theres no best way, there can be several approaches. Can you wrap your head around that? If i water every other day, its not treating coco like soil. Why make no sense offtopic comments, what are getting out of this?

It is actually the best way how to treat coco.

There is a best way, the way that gives the fastest growth in veg and optimum flowering.

Granted you can treat it how you want for your own convenience but there's still a best way for the plant.

this can be checked with a slurry pH test for the coco using distilled water and a sample of the coco etc.

I've read this before. How is it supposed to be done? Everytime I grew in coco it's roots all the way to the surface... Seems hard to take a sample. Especially one that would represent the whole medium.

I was under the impression that you were looking to optimize your feedings, at least that’s what your original post said?

Multiple small fertigation events daily is optimal for coco. If you’re looking for alternative feeding solutions that aren’t optimal you should have said that. Yes you can feed coco every other day and have a successful grow but it’s not optimal.

Yes i guess i have to get the stick kind of hp meter what you stick in the medium.

Altough i was wondering some kind of syringe suction sample too. Like the dude above, i dont like the idea of taking medium out. The roots are right on the surface.
 
COCO measuring method
The most reliable method for measuring the nutrient levels in coco is using the 1: 1.5 extraction method.
EC and pH of the root environment can be determined by using this method. The pH and EC of the drain water generally deviates from the actual root situation, as coco is able to retain and release elements.

Take a sample of CANNA COCO from the slabs or pots (photo 1). This can be done with a soil core sampler or a trowel. To get a representative sample the coco must be collected from as many places as possible.
Collect the sample in a bowl and determine whether it contains the right amount of moisture. The coco has the right amount of moisture if moisture disappears between your fingers when you squeeze it (photo 2). Add demineralised water if necessary and mix the coco.
Take a 250 ml measuring jug and fill it with 150 ml of demineralised water. Add coco to the 250 ml mark (photo 3). Fully mix and allow the slurry to settle for at least two hours.
Mix again and measure the pH.
Filter this material and measure the EC.

A 1:1.5 analysis can preferably be done after 3 to 4 weeks. The target values for EC are between 1.1 and 1.3, for the pH, between 5.5 and 6.2. Very high EC values increase the risk of burning symptoms. To limit the risk of burning symptoms, the coco can be rinsed with acidified water (pH 5.8: acidify with CANNA pH - growth

Depends very much what kind of setup are you running. You dont even know my circumstances, so no, multiple daily feed isnt "the only most optimal" way for coco plainly. Now comments only on the subject please.

You’re not only wrong but you choose to wrongly believe you are right.

In order to get the best performance from coco, or to “optimize” it, it requires multiple fertigations daily. It has nothing to do with your circumstances.

Just because your circumstances don’t allow you to optimize your coco it doesn’t mean there isn’t a better method for optimal output.

If you want to know the optimal hand feeding method for your circumstances that’s completely different then optimal overall. Hand feed your plants as many times daily as you can. If you can only feed once daily then feed them to significant runoff. Allowing dry backs by feeding every other day is just asking for problems with salt buildups and EC spikes.

You can do what you want, they are your plants after all. But you are the one that came here asking for advice.

And for what it’s worth I only hand feed my coco once daily. I’m not optimizing my coco.

Geez, heres your 10 internetpoints. Now please stay on topic if you have to comment.

It was on topic. You already got your answer.

Trickster52 said:
So can you conclude that ph levels rise up slowly, and can go beyond hemps preferred levels? Or is it that simple?

pH will fluctuate slighty over time. Since coco is frequently fertigated the coco will reset to the feed pH as you feed to significant runoff.

Yup, it’s that simple. You’re trying to turn this simplistic answer into some type of theoretical advanced cultivation topic.

Yes. And i want to know, does it go up or down, and in what cases? I want to know that. That you havent tell me.
