That's exactly what I was thinking, was it over 89%???
I thought you were getting tissue analysis.
It is pH driven. But if you are at a 6.4 pH you sure as hell don't need 85%. If you are over 7 you best be measuring tissue samples cause it varies all over the map depending on the pH of your fertilizer.
This shit is driven by light. There ain't no one size fits all solution. Measure is my suggestion. Anybody that says different is full of shit
measure
What issues are you seeing at those levels?
So what do you think the ideal Ca % is and at what moment in time?
And what % Ca did you hit to get that 10% Ca in the foliar analysis? What soil analysis procedure did you use to calculate this Ca% in the base distribution?
How about sharing this leaf and soil analysis here on this page?

Sounds like you should read Tiedjens..... This shit is driven by light? Oh, please explain...
Sure seems you like to push the extremes for what ever reason.
As for pH, folks put way too much value in it as they don't understand what it means.
Love to see your measurements. These comments coming from your experiences with those meters? Or from where?
If I could magically get soil pH to come out exactly where I planned I would pick 6.4.But the truth is I never see the math work out that precisely. If I get between 6.2-6.8 I am happy
I find P and Cu the hard things to get cannabis to take up. I am gonna give up on Cu and just spray one of the glycine foliars. So far I have not found a foliar P that works for shit

good morning slow >>> i saw you mentioned Regalia in another thread ...has your experience shown you that this is an effective product?? & will it store over winter in an opened (but sealed) container??? ...peace
There is a lab in CO that can test for legal grows. Tissue test using ICP
And they are all perpetual so if one is so inclined one can see every week of veg and flower at once
The trick is keeping my beliefs out of it, designing good experiments and following the data
the ability to get that snapshot of the entire crop life at once is way cool
Saw some pretty amazing control in Laytonville. This grower typically had huge problems, this season, with all the things we did in terms of nutrition, the only fungicide we used was Regalia. He had a great season! One last application in early flower and that was it!
No idea about the storage over the winter. I suggest calling the company and inquiring.
Did you use it this season? Care to share your experiences?
I agree completely. I would argue though that your thinking historically has been linear. If it doesn't show up in your meter, or even in your leaf analysis, doesn't mean applying more is the answer.
This is why experimental design is so important.
Heard Reading was managing a grow in California, you know anything about that?
You can always apply phosphoric acid at half a point or so. Works great.
Give up on Copper? Wow.

I did use it as a foliar and the product itself is not offensive
but i was late in my application (as a preventative) and could not get the results i wished >> some damage was already done by then (leaf spot)100 bucks says the regalia had nothing to do with it.
I battle the PM fairy every year. This year? Nope, still have plants with zero mildew out in the field wasting away. Same with my bug problems. Bought beneficial's around flowering and never sprayed again. The cleanest harvest I have ever had, period. Plant health, with high levels of calcium early is the only defense against PM. That and tissue cloning. At least Regalia claims to be systemic, as oppose to green cure or something like that. However Actinovate claims to be systemic as well, but that stuff blows.

Wanted to post this for everyone doing tissue analysis, from Marschner book(11.4.1). Seems a little incomplete but made me realize it may not as simple as rinsing with water:
Also are you guys analyzing flower tissue or just leaf?
Also are you guys analyzing flower tissue or just leaf?
The pH of a 0.5% phosphoric acid will be 2.1 or so.... that scare ya?
This is true. The past two years some of the places I've worked with have called me late in the season when the problems start (pm begins with August humidity). The soil was just not amended well enough, 60% Ca saturation. Regalia is effective, however. It will significantly slow down the progression of mildew, but you're just treating the symptom.
