OP.

My thoughts originally was potassium issues. It's common in coir.
Potassium deficiency locks out calcium, magnesium and leaf tips thin and burn.

It's important to know your waste though. Because if the ph is low it'll lockout all of the above.
It's what I think is happening myself. You most likely have low ph causing lockout. Plus too much nutrient.

Find out the ph and ec's of your waste, the next time you feed.

I'll upload a good article about coir from canna for you.
I'll upload a handy chart too.

Listen OMU, im not a scientist , guessing your not either. We all take in info and judge the source. This source seems legit to me and therefore i passed on the
info here about ariflow and non mobile nutrients.

Actually I am a bit of a scientist after going back to tech school in my 30s and earning a diploma in environmental chemistry good for 2 years uni credit.

I don't watch videos online. Biggest source of mis-information until Trump came along.

and from another source.

"Since transpiration and calcium flow within the plant is so heavily influenced by the environment, lowering humidity and increasing airflow across the foliage assists with boosting moisture loss and calcium incorporation into new cells. However, while lowering humidity from high levels does boost transpiration, a very low humidity can result in other problems."

the article was written by Dr Lynette Morgan who is a PHD in hydroponic greenhouse production.

NEW cells. That's where Ca goes and that's where it stays.

Says nothing about a breeze picking it up and moving it somewhere else in the plant. Once it's in a NEW cell it can't be utilized somewhere else if the plant runs low on it like it can with a mobile nute.

You've proved nothing but your lack of understanding about the difference between mobile and immobile nutes and how the plant makes use of them.

Try again. You sure missed the mark with that retort. You seem to read and write OK but you seem to suffer a lack of comprehensive skills.

I'm totally in agreement that the right humidity levels and good air circulation is going to benefit the circulation and utilization of nutrients in the plants. That's nOOb 101.

I own a few of these and have read quite a few of these digital versions. My first grow book was Grow your own Stone by Alexander Sumach I bought in 1978 when I was growing my first buds.

I found a great spot to download FREE POT BOOKS. I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as some are 50+ megs. They got lots. Enjoy.

So you believe the media over Trump too? wow. Do yourself a favor man, stop watching the news. The news is controlled by major corporations to push their agenda.
Trump has lowered taxes, killed regulation and has just about shut down the retard in N Korea. He has done more in 2 years then Obama did his entire 2 terms... unless you count drone strikes,

BTw, never said that air blew the Ca around the plant, so your reading comprehension is lacking. My guess is this. You started a long time ago growing and have been successful through trial and error and therefore you are not even trying to learn anything new. Air circulation helps the plant move Ca around period. Lack of airflow will hurts the plants ability to move Ca around the plant.

Case closed.

The terms “Mobile and immobile nutrients” refer to the transportability of these substances within the plant. This classification is primarily oriented on terrestrial plants — in aquatic plants the transportability may be somewhat different for some substances, as these plants’ entire tissues are submerged in the nutrient solution. All in all, however, a classification is possible anyway that can give clues as to the deficient nutrient. Mobile nutrients are nitrogen in the form of nitrate, phosphorus (P) in the form of phosphate, potassium (K), magnesium (Mg), chlorine (Cl), zinc (Zn) and molybdene (Mo). Calcium (Ca), sulfur (S), iron (Fe), boron (B) and copper (Cu) are immobile.

Im trying to understand so bare with me

I get mobile and immobile.

But is the guy saying,

When the nutrient was originally headed to its intended location it was unable to make it all the way due to transpiration Issues and was stopped short.

Now if you address the transpiration issue will the nutrient continue on to the intended location where it will now become immobile.?

I think so. Yes. I suppose it's possible too. But I would assume transpiration issues would affect all nutrient availability?

Imo it's more important what's available at the rootzone.
Such as sulphur and calcium aren't nearly as available, when the roots are cold.

I think it would affect all nutrients but maybe some first.
Im just playing devils advocate.

no, it won't. thats part of what immobile means. it gets transported to where its needed, then it gets bonded into things like amino acids and lipids the plant needs to build itself. it can't break those bonds, thats what makes them immobile.
mobile nutes are carried in the plants phloem and xylem and taken by the plant as needed, and can even be reabsorbed from older growth and redistributed to newer growth.
some of the "immobile" nutes can actually be mobile, if there is too much present, the molecules that can't be bonded can remain in the plant for quite a while, till they are actually needed. of course, this is also the first stage of toxicity

as far as air causing nutes to move...NO..air movement can cause lower rh, which raises the plants transpiration rate. that will cause increased nute use. however, if you raise the humidity of that moving air, transpiration won't occur, and the increased air flow has no effect. so it's humidity, not air movement that causes transpiration.

Lol. You funny fukka :bigjoint:
I already made peace. Not getting involved.


But.
I will whole heartily agree, Trump is a fucktard.
Trump needs to go. He is like an infant running the White House. It's quickly damaging the rest of the world.

Cool.
Ph looks pretty good.
Just check if your ec's are the same.
Hear from you soon.

Should I do a run off test or slurry test And should I use distilled water. And if I do a run off test should I use distilled water to get the run off sample. And should I will do a controlled test with ph and ppm level before the i test
