Agreed.

For my coco dtw....
Now that I've used both, I prefer Jacks. Well established with many using it. My ph is more stable, and much cleaner res and lines. Better control over N levels. For coco, MC is kinda high in K out of the bag.

And there are several other brands of 2-parts similar to Jacks.

?????
As for the latest MC not dissolving as easily....
The powder may be (ideally! Hopefully!) designed to dissolve the different granules at different rates. To prevent precip from chemical reactions between the base and calnit.

The more I learn, the more I dislike MC because it's a 1-part.

And....I have used GH trio with sucess. Would rather use it than MC.

Yup. Agree with all the points of Jacks over MC, and the "learning" more just in time to regret it, hah. No experience with MC in coco and K issues.

Probably why they have so much what looks like molasses in there to keep the chemicals from reacting, similar to what GH does with Flora Nova with lots of organic shit in it to keep chems from biding/falling out. There's lots of powder only nutrients out there. Some over priced some not as bad. Back in the day sold tons of 5-50-17 (root and bloom used in the first week) 20-20-20 (veg) 10-30-20 ( flower) add in MKP (0-52-34) once a week 3,4,5,6 and then 5-50-17 the last couple of weeks. Really what else do you need?

Some type of humic/fulvic acid maybe..?

Too sticky to be humic but probably humic in there too. It also smells like molasses lol.

Anyone notice you have to quite a bit more mc 2.1 to get 1000ppm? Seems the new version needs more than previous. 5 gallon pale..tap water is 150..added 22grm of mc2.1..and 3grms of bud explosion.. 750ppm..and i have checked my tds pen with confirmed distilled water of 20ppm. Does water temp play a factor on ppm? Water is 17degrees.

I think you might be right. It might take a little more MC with V2.5(?) to reach the same EC as with V2.0 (or prior?). But the EC (ppm) your meter is reading isn't really the best indicator of what's going on or how much of the elemental nutrients are actually in there. I'm just trying to say that by the time I'd figured out how much MC to use I was way over the "meter EC" than I thought I "should" be, comparing to using another brand of nutrient. i.e.: 1000ppm of MC doesn't equal 1000ppm of Jacks (full strength) doesn't equal 1000ppm of Canna, etc.

I'd suggest maybe check out MC's elemental nutrient calculator on their website, and have a look at what *should* be in there elemental ppm-wise, based on how much you're using. Then, you can compare that to other brands you're familiar with what ppm you think you should have (online ppm calculators). Hope that makes sense/helps.

Oh there's definitely both in there. There isn't a plant input known to man that isn't in MC, lol.
I was just guessing at what might stop binding, but didn't think humic was a great guess (as I mix up "extreme blend" and the amino and humic is incredibly hygroscopic, haha). It's just a mass of black tar now.

Hah I remember having some bags of Calcium Chloride and they were wet as fuck lol as the stuff just absorbs moisture.

There is a film in the bottom when i go to brew a new batch.. previous version did not leave as much film.. after this mc2 is gone..i might be heading to jacks..

Once you go Jacks.....


(GLN constantly reformulating - I can wait until they have a solid product...maybe 2yrs from now. Let others do their beta code field testing.)

Yea, it leaves a little sediment on the bottom (settles out after a little while). I never noticed it smell, or be slimy, I don't think it's "biological" or anaerobic nasty shit. Just a nuisance and could be bad for clogging, maybe.
Jacks looks clear as water the whole time. Unless you use some colored cal-nit or something.

Yep. Jacks very clear and clean....but that changes the more crap thats added. I add some floralicious plus, it leaves a film!

Anyone hear rumours greenleaf going to 2 part? Would it be the same as jacks 5-12-26?

Also...anyone have a breakdown of salts if i wanted to replicate jacks 5-12-26? In leamington ON there is sun parlour cannabis supplies (county road 31) for the huge greenhouses here.. i can get all the nutrients to make jacks.. i was in there and they even mentioned if i know the breakdown..they could blend it for me..and cheap..bought calnit 50lb bag $22. Looks like my veggie garden will do great this year as i can't use all that.. aquaterra..i would get it from you but the shipping price is more than jacks..

I have what looks like calcium deficiency with MC v2 in flower..i am in coco and i reduced the recommended amount as i added bud explosion..i wanted to cut back on N. 22gr and 7gr (BE) in 20 litres.

There's no escaping insane shipping charges in Canada even with discounts especially Canada post. Canpar can be quite a bit cheaper but I read too much negative on Canpar, besides shipping from BC to Ontario even if I do free shipping and charge MSRP prices I make no money or lose money on nutrients orders. I'd have to spend $7800 a year to get up to 30-40% off CP shipping which even with that being a store in BC is not sustainable to east coast orders.

I read of people going across the border and shipping from US to Canada to save their customers on shipping charges.

As for Megacrop I'm not really gonna bring it in anymore as my current supplier doesn't want to re-order even though I've sold like 60+ bags. I'm gonna test out growing with Jacks and a couple other powdered mixes and see how it goes. Also gonna try Technigro 9-45-15 20-20-20 and 10-30-20

Using MC or Jacks, I have experienced ca defs in coco.

This helped....

I use GH CaliMagic
Fewer problems when I buffer the coco properly.

Once thing I noticed using coco specific nutrients, at least when I tested with Canna it was much better than using Canna Substra+ Calmag or MaxiGrow/Bloom + Calmag.

Whats the price you were paying for Jacks 11Kg and shipping? Well either way shipping to Ontario would be around $40-45. 15kg of chemicals to Ontario was $47 on an order last week. My online price is way different than in store price same with say Gavitas 1000W DE. Might be different in Ontario but in BC local buying for stuff like electronics is cut throrat.

Thanks for posting that AquaTerra
That's was very informative for sure. I appreciate you posted it.
And yes shipping rates suck with you being so far away.

No idea what the coco specific nutrients worked so good vs nutes+cal mag, I switched to them after seeing issues and the change was night and day over two days.

Ya I'm using Canna Coco and don't see a lot of CAL MAG issues but that article will have me looking even closer now. Interesting how the Coco is more unstable at first. I may start adding more in early flower as they are in the new coco at that point. I've been using Calimagic for a while now.....whew. Didn't know it was better that some other supplements.

Canna coco is the best I think plus its the cheapest wholesale by $5 plus I like Canna as they never really had many bottles in a feed schedule vs 15+ for some manufacturers. The baller grower days are over, make it smile no one is going to buy 20 bottles when weed is $800-1200lb.
