I am personally having a very hard time trying to incorporate past teachers lessons (such as those ag videos) into the new high Ca paradigm. SlowN needs to write a book, lol. SlowN guide to high Ca cannabis. Lesson one, gypsum.

Every chapter would be gypsum.

I'm probably gonna have to get a pallet myself.

Funny guy you are reppin..

Calcium(s) is the first lesson. The lesson is not gypsum.

Gypsum is a source of Ca. You can't go to lesson two til you learn lesson one, no?

Once people learn how to use Ca they immediately need to learn the other lessons. Things have changed, dramatically. That is the shocker we have seen in nearly all cases. The plants DEMAND more food. Makes sense.

And what is that complete Ca lesson? Predigestes carbonates so as to add a good source of calcium without having to drive S through the roof using gypsum but not using that much where we drive pH past 6.7 or so. Calcium(s), yes, lactate (milk), silicate, carbonate, sulfate, gluconate and phosphate come to mind.

do you think the more sources of calcium the better for Ca uptake? or all for different applications in different soils at different times.
If our carbonates are predigested will the M3 test become closer to the AA 8.2 ppms of Ca, Meaning less unavailable calcium showing up through both tests?

1-2-1 is npk ratio of fertigation feeds, I would think. And top dressing for that matter.

HTF, I think he advocates so many different calciums because the base saturation levels in the soil are so high, any one source of Ca would tip the scales in one way or another. Too much lime, has too much Mg. Gypsum too much Sulfur. ext ext. So getting the ph to the 6's then using gypsum seems to be the key, right slow?

Next year, loads of bone meal up front, with some gypsum, alfalfa and metals.

I know most of us have yet to finish a crop with this paradigm. However I think we can all agree the nutrient uptake is crazy demanding when farming with high levels of Ca. But is it worth it? I have dumped literally tons of amendments on my soil this year, and it's costly. However, if the quality is there, it's all worth it right? I got the quality in my deps, but not the yields. Looks much better in my full season.

Any comments?

You only get one swing with the big bat per season... If you are chasing your tail making micro adjustments, that is where your costs over the season will add up. Time, labor and amendments...

Metals shoot out of my soil. I need to add them weekly or they would be at 0 ppm real quick. Thats why I liked micropak. On top of that, I would add 1-1.5g of Mn and .5g of copper. All year, weekly.

Absolutely. Weekly fertigations are a must. Keep that balance

Well I'm half way through my third read of this thread since last fall, and am hope the fourth time might be the charm!

Being indoors I've had a few attempts at interpretation so far, running into problems predicted here, learning and adjusting. Never knew Metals, neither does GH from what I am now seeing...

Crazy feeding? no - scary feeding, yes! You need that when you're growing Saquaro-like stems. I do believe I'm undershooting at 2.4ec...

The response to LST is substantial and vigorous. Quality improved quickly with more stink, higher trichome fill rates and fuller ripening. Yield needs focus from beginning to end.

Happy,

Yes, the more varied our calcium sources, the better off we are.

And yes, predigested carbonate is a great source of Ca and the M3/AA8.2 Ca ratio will be tighter or closer.

Those that had old mixes had much higher Ca using [email protected] than those using just gypsum as their source. And it is a much more stable form of calcium, much less prone to leaching away.

How long does it take carbonate to become available? 6-12 months or longer? I used Gypsum and wollanstinite as my Ca this year, happy with the Ca results from logan about 75% on the AA, but when i did my spectrum tests i felt like i was starting at ground zero again, a month later and spectrum says 64-66% had the plants taken up that % of Ca in those 4-6 weeks or is it just normal to get such different numbers from each lab. Can i predigest Carbonate with some sort of enzyme before using it in the coming season, or this term "predigested carbonates" just means calcium carbonate has been in my soil for more than a year or so? Thanks for the response Slow your very helpful in my learning process

Thank you slow and others.

Thank you slow and others.

I would not have hit the numers i have this year if it were not for this thread. I will ve hitting 12- 15 units a plant but that is far better then my 5.5 last year . hopefully if i send soil test in i will be able to balance my known to produce dank recipe with the high yeilding commercial side of things . my goal is still to brake 20 unit's a plant within 3 years and to brake the oregon record after 3 years.

My girls this year.

When we are applying mix of gypsum + calcium carbonate with organic materials does addition of Ammonium sulfate helps in Ca release due to NH4 occupying Ca sites ??

AS is problematic with this style growing because of the sulfate. Biotic style ferts are better. They stimulate microbes which break down the carbonates, etc. Malted seed meals (rye), ala coots, work very well also
