Thanks.
I assume it was humidity. My frickin dehuey unknowingly shutdown for 2 nights in a row. Drain line was pinched.
No biggie. I have plenty of stash.
Time and effort down the drain.
None on the Green Ale show PM....yet. doh.

I use a UVC light, zero mold issues. It’s not directed at the plants but all the air in the room is passed across it.

Great pics and info. I grow in canna coco, and have been adjusting jacks mixes for years. I use pure ro, and pure coco. I just can't get my veg formula quite right. I have found almost all my strains need more calcium than standard jacks 321 provides, and I often struggle with mild mg def in early veg. I am now running jacks in the 3/2 ratio, but not adding any epsom. Instead I am adding calimagic, starting with 3-5ml/pg before adding jacks 5-12-26, then calnit at 2g/pg. Plants seem to be responding well, but I have learned not to get my hopes up. I am close to switching to something different (besides jacks) for my veg and mothers. Previously (before calimagic) I would have to add near equal parts by weight jacks and calnit and varying mg to get decent results. It's been frustrating trying to get things dialed.

Thanks for checking it out.

Bummer. Do you have a grow log so I can learn about your setup?

For me, running a PH of 6.2 really helped with Mg issues.

I have done, and still do the same...
Supplementing Calimagic to bump up my Ca/Mg during veg.

Bagged Canna coco? Do you prep the coco in any way before using it?

Pot sizes and feed frequency matter.

Nutrient levels and nutrient balance

PH affect on Ca MG uptake.
Also confirms why we want 6.2ish during flower when they want the P.

This recipe has worked well....for me.



On the Calnit.
I am using Haifa calprime. Has just a touch more Ca to N.

I've never used more than about 150ppm of Ca

Yeah, I'm using canna bagged Coco. Used to use botanicare bricks. I am still hand watering, but plan to automate soon. Growing under sunsystem dual 315w in veg (but only using one bulb at the moment) ro water, no c02 supplementing in veg. The last few months I've had a break from running the flower room, so I've been trying to improve my veg mix. I don't pretreat the Coco, although I have in the past. I could write a book telling you about all the things I've tried and what my conclusions are, but the biggest thing I am perplexed about is why I seem to need more calcium than most. Before I started messing with calimagic, I often would use a ratio of 3g jacks to 3.25g calnit for the first few weeks. Now that I use bagged canna, I seem to do better with equal parts jacks and cal by weight, or slightly less cal. My normal pH is 5.8. makes sense to raise it some for uptake. I am guessing once I automate watering I will have fewer frustrations. Once my plants start drinking faster, I have less issues. I'm currently running yaraliva calcium. Thanks for the tip about calprime. I'll check it out. I've been enjoying your posts, and they caught my eye because we have many similarities. Thanks again, I'll keep you informed.

I've used YaraLive. Good stuff.
"One gram dissolved in one gallon of water yeilds 41 ppm nitrate nitrogen and 50 ppm calcium."

I have PureCal on my wish list.
34.32ppm nitrogen
47.52ppm calcium.

Nice. is that exclusive to custom hydro nutrients.com? I am trying your veg mix, but have a few questions. You use i ml per gallon of calimagic correct? Also, you are watering down that mixture to get 1.34 ec right? I end up a bit higher.

Yes. Adjust EC by diluting as needed with extra RO.

Do not know if exclusive to Custom hydro

I prefer to use a calnit.
Use Calimagic only as needed.
I use it when I need the Ca, but want to keep my N lower. Usually in combination with lowering Calnit.

I've been running 1.4 and 1.6 ec.
The right side of my feed sheet posted above shows PPM at different ec.

(Approx 1.5ec elemental PPM)

What is your jacks veg formula (amount per gallon and resulting calculated elemental ppms?)
What exactly is the issue or visual symptoms of the plant/leaves that you think means calcium and/or magnesium deficiency, have any pictures?
What are the parameters of the room?

This looks like great stuff. How does the regular Jack's calnit compare to it? Thanks for mentioning this site, they have some interesting products and great prices.

Lookin' good, Tint.

Green Ale


The gang of 6

Had a bit of effin PM this run.
3 into trash.
3 three step washed.
Good for practice, but it will probably get tossed. It's all personal stash. Fortunately I have plenty of reserve in jars from past grows.





I'm thinking about tearing down my grow spaces. Start over when I'm in the mood.
