That's great man. Sounds good so far.

Glad to hear the MC2Part is solid so far.
New greenleaf calculator allows for diddling with PartA and PartB.
PartA is the base. With micros. Zero Ca.
PartB is calnit. Ca and N.

Fertilizer Compatibility
When mixing fertilizers, it is important to check fertilizer compatibility before application. If incompatible fertilizers are mixed, they form insoluble precipitations that can clog drip emitters and damage sprayers used to apply foliar fertilizers (Figure 1.). This article discusses a few scenario

Based on their feed schedule you get the following Mg ppm:
Early veg: 25ppm
Late veg/ early bloom: 42ppm
Full bloom: 70ppm
I feel like the early veg might be a bit low but that's based on lucas providing around 60ppm. I suppose it will end up being strain and water source dependent. I was adding epsom to my cali orange but that plant seems to have a new issue every time i blink.

I was basing that off the 3-2-1 formula and just seems, compared to the calcium levels, the mag would be out of proportion.
But I do run in coco under cob LEDs and have come to realize what many consider “cal mag” issues can be corrected by just increasing mag and leaving cal where it was.
Ok so I got my “Part A” in today and just opened it and mixed up a concentrate just to see what it looked like and how it dissolved and to see how well it stays dissolved over time.
2 things I noticed, this stuff reaks like cheap big box store granular insecticide and also make sure to dissolve in large amount of water. Don’t slowly add water to the powder as it gets very exothermic. I added 100gram to an empty 500 ml water bottle. Rinsed out the cup I weighed it in, 100ml and used that as the first water added. By the time I got the distilled water jug and grabbed the water bottle it was VERY HOT. If I hadn’t instantly added the remaining 400ml I guarantee it would’ve melted the thin plastic water bottle.

So far so good with the two part Megacrop.
Plants haven’t skipped a beat, ripping along nicely.
PH in a 55 gallon reservoir is holding for 3 days very consistent.
A slight drift from 5.8 to 5.9/6.0 on the Guardian, but that could just be the solution stabilizing.
I’m adding Velokelp intermittently, and Orca for bennies in every reservoir.
I always use Orca or Great White. Unless someone can suggest something cheaper and that’s just as effective.
I mix, and it’s used right away. I don’t let it sit. PH it real quick to 5.8 and rock n’ roll.
Still using the one part Megacrop in a 35 gallon for veg. It drifts up .1 to .2 points a day. I do like the one part for veg. Simple and effective.

Ive been using the 2 part for both my veg and bloom for the past few weeks. Im about to be w6 in bloom with only the 2 part MC. Looks very very very good. I had some deficiencies...not sure what it was exactly..... but I believe I stopped them by bumping up the EC.
But I think ill go back to the one part. 2 parts too much work for me with the differing ratios at each stage of the cycle and 2 nutes instead of 1. Frankly, I dont even believe in that extra nitrogen in veg.....increase P and K while budding nonsense. Ill just finish this run following the recommended ratios at the plants cycle just to see what it turns out to.
I still get some sediment in my rez with the 2 part. its from Part A. I mix it with a drill so it definitely isnt from my end. Friend who uses Jacks 321 saw my rez and said "looks nasty....Jacks is crystal clear with no sediment at all in my rez." lol.
Nowhere near as bad as the previous version of MC though. MC 2.0 was a nightmare for Hydro but it performed fanastic just like this new version.

Ppl are using way more expensive stuff these days like Tribus and Mammoth P for hydro. A tiny bottle is $80 bucks. I looked at the ingredients of Tribus a while back and GW has 4/5 bacteria strains that Tribus has + a bunch more. I remember Tribus was very very concentrated though. Much more so than GW....but Ill take GW's lower price and those 10+ extra bacteria strains over Tribus/Mammoth P.
I think some smaller growers vouch for Photosynthesis plus but according to the directions i think i had to dump in 500mL of that stuff for my 70 gal rez. Dilluted af.
So yeah.... I just stick to Orca or GW for hydro. Slightly leaning towards GW over Orca though after testing Orca for the first time last run.
I noticed this sediment too In my attempt at making a liquid concentrate. I originally put 100 grams in 500 ml and this morning has tons sitting in the bottom of the bottle. I added another 500ml and still have some that won’t go into solution and it also has a foamy head that won’t go away.
It’ll be another few days til I need to mix up a regular strength batch but I’m hoping it’s just a concentrate issue.
As for the concentrate I’ll just use that on my vegetable garden since it doesn’t seem to be practical for a res and storage.

I just mixed up a 55 gallon reservoir. Had the time tonight so I snapped some pictures. I have an aquarium pump in the reservoir to mix for me and the pvc to “blow” the little bit of shit off the bottom when I first mix:
150 grams of part A:
Nothing on the bottom. Next is 70 grams of part B:
Looks fine on the bottom. Now a little cloudy.
After sitting:
Looks fine. Nothing on the bottom. EC 1.3 and PH 5.5.
Add some bennies and a little PH up to 5.8/5.9 and it’s good to go for me. The PH holds for the 3 days it lasts.
The amounts I use is about 65% of the full strength flowering proportions for Part A and B.
Part A doesn’t smell like much till you get close. Then it’s chemical dog food smell. Lol.
So far so good!
Day 42 after flip. Multi crop/coco/DTW.

That’s good to see, I’ll just mix it up as needed and leave the liquid concentrate alone.
Here’s a couple pics of it at 50gr/500ml.
And he’s what it looks like shook up

Oh, not good. Thanks for posting that, I was going to try the concentrate route as well.

I noticed you mention adding water to the fertilizer and maybe that's the reason for the precipitation. Have you tried adding your 50g to water not water to the 50g. I saw a blog entry on the greenleaf website and it mentions making 100x+ stock of the 2-part and you would be at around 90x with 50g of part A in 500ml so I would expect it to work (assuming the bloom schedule of 4.2g per gallon).
From the blog entry these two quotes stuck out. I dont know if it helps at all. The link to the full blog entry is below.
"Also, during the initial mixing , if you slowly mix and gradually stir in, there is less likelihood of precipitate forming"
"So, right now the only group really harmed by the solubility issues mentioned above are fertilizer injector users. That is why we plan to release a Mega Crop 2-Part formula in 2020, which would solve this problem and allow fertilizer injector users to run at extremely high concentrations 100x + without precipitation or solubility issues. As for the CalMag issue, we want to have a CalMag with lower N and higher Mg, since most of the issues people purchase the product for are Mg related. We have a few different options available now, including the option to even release a new pure Magnesium (Mg) product standalone."
