The pH of a 0.5% phosphoric acid will be 2.1 or so.... that scare ya?
Little bit but I have sprayed kombucha at 3.5. A one plant trial ain’t no thing though. Thanks

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.
If you don't mind sharing what metal sources you used?So it was the metal regimen you had me on. For sure never added metals other than kelp before a few years ago. Seemed to get it dialed this year, thanks slow!

Anyone have any experience spraying Cease / double Nickell 55 for mold prevention? I've been tank mixing the two at low dose, spraying every 4th day. I like to water regalia into the soil.
I've been dealing with 90+% humidity in my greenhouse - not a speck of PM but botrytis is definitely around
As much as I would like to say high Ca saves the day, I believe it has a lot more to do with metals, zinc, copper and manganese.
One grower this season had high Ca, well over 75% and yet lots of mildew. He never got close to the Cu and Mn that he needed. His pH was reasonable too. Problem was way too much Fe.
Again, many times linear thinking doesn't work in agriculture.
If you're shooting for high calcium, what ratio would you want of those and what levels. I have seen you say in this thread you do injections of 400 ppm of Mn (if i remember correctly) and than would want a Mn:Fe of 1:1. Zn I imagine would me much higher, but how high
No, not 400 ppms at one time... NO.... Ideally you can work from 1 Mn to 2 Fe... 1 to 1 is even better.
Zinc would never be higher than Mn... not even close.
Zn should be about 10 to 12% of P.
In a bit of what if, what would a soil report from Spectrum look like as far as all the numbers look like if you could pencil in the numbers you would think as just about perfect ?
Or can you share one that comes as close as you have had that is just right as far as your previous grows.

I over apply what I am trying to balance. Injecting in 300-400 ppms of Mn into a nearly field capacity soil, knowing that that "heavy" injection will spread through out where there is water.*
I do this sometimes twice a week if necessary with fulvic acid. 4 grams of Mn Sulfate in a gallon of water is about 340 pppm of Mn.*
At the end of the season, the Mn in the soil may have more Mn, a whole 4 or 5 ppms more.*
I think they were referring to this:
Doesn't work that way. Balance your soil based on your CEC, pH and nutrient levels. Every soil has an appropriate balance of nutrition.
It would seem that a good bit of growers haven't looked at the Soloman worksheets...

Go to the bottom of the page and you can find the different soil worksheets. These will give someone with no idea of good soil numbers a chance to get on the road to recovery.
Balance is key...
Slow posted way back .1gr Cu, .2gr B, .3gr Zn, 1gr Mn. That equals something like 8 Cu, 6 B, 27 Zn and 85 Mn ppm per gallon... Is that accurate slow?
:
How much Cu is in your soil and what is the pH? Chances are you will need to spray...acetate or glycine will work so whichever is easiest for you to get.
Ca 75% at least, k 4 or below...yea?
PAR 800 or above (concern is nitrate not converting to protein)
