Jack's 3-2-1 question

[Skybound420]

My feeds are based on Megacrop, though I use a lot more P, and less K, also I use a lot more Si.

Here's a link to my Bill Of Materials. MAP isn't included, but that's the only one I bought after writing that up. The micros will only need to be purchased once. Here's where I get most of my stuff, but Greenway also sells some, Build-a-Soil, Amazon and likely other place. Aint gonna lie, shipping is costly, but IMO, it's still worth it.

I use the following;

Haifa Calcium Nitrate
Magnesium Nitrate
Epsom Salt
Potassium Sulfate (SOP)
Potassium Silicate
Potassium Nitrate
Monopotassium Phosphate (MKP)
Monoammonium Phosphate (MAP)

189.27 grams mixed into a half gallon of RO to make a 1:10 concentrate. I round that 189.27 up to an even 189.3 so I can use the bigger 0.0 scale because it's a pain in the nuts to weigh out stuff in the hundredths range. The 0.00 scale is needed to make a micro mix though. Once micros are mixed, I only target macros with Hydro Buddy and when it has the above compounds to utilize, it achieves my targets flawlessly with zero error.

Ok... I'll get a laptop and start looking into salts. Thank you.

Any particular reason for basing on MC?

On 420, there's a grower that I respect named Farside05 that grows with MC, Silica and Calmag that always had flawless looking plants. He also reverse engineered Pro Mix, and since I use his Faux Mix, it just seemed like a good recipe to model after. Like I said, I changed P and K as well as Si, so my blend is very different than what he uses, but it was just a starting point. Well, that was MC's last formulation. They've since switched up their game and now MC models their line after 321 believe it or not. That too made me laugh b/c they sold out IMO.

MegaCrop doesn't really have that much Si anyway. I think it's mostly in there for marketing purposes and pH buffer. How many ppms of Si are you running?

20 in veg and 40 in bloom. Farside does 50 the whole time.

Thanks man. I've learned a lot today.

Good discussion.

I've evolved from bottled nutes to jacks, and considered doing salts. Keeping in mind I only have such a small 4x8x8 hobby grow. Coco DTW.

Curious what you guys think of this yet to be tried "funky freebase" formula I whipped up. Using premixed micros. It's about as deep as I would want to go. No mixing my own micros.

I hear mixing micros can be a nightmare. It's one of the reasons I haven't looked that deep into it yet. I think i might start experimenting with it though.

Was definitely not referring to your plants by the way. I was referring to the person that makes money by reviewing their products on youtube and similar platforms and spreads misinformation for their own benefits.

Jacks 321 is cool, I'm using it. But I don't think it's geared for Cannabis as much as they say. Like someone else said earlier, it runs hot and is also low on P. That's why people are buying supplements.

There are a ton of great people on this website. And there are a ton of really shitty people on this website. I'm just trying to open people eyes to consumerism and commerce. People are being paid to review things, of course they misrepresent them, to Make Money.

Who are you talking about then?

Well...I thought he meant me... but I believe he's referring to greengene.

Greengene gas had a few shit crops when he was trying different recipes, but if he's saying greengene can't grow, thats hilarious. I tried looking for pics of his grow but can only find him giving info to other people.....

3,2,1 isn't their cannabis designed product. They have about 4 or 5 different lines more geared toward weed, but the 5-12-26 is the one that's been out and worked with the most. Have you looked into their other lines to see if their ratios better suit your needs?

Not yet. I just started with jacks a couple months ago. I'm still working with it.

By my estimation, your P is severely toxic, N is too low and it should list how much nitrate and ammonium is used, Fe is too low and the rest of the micros are okay. Mixing micros is easy as long as you target each element in good ranges. Learning Hydro Buddy is the hardest part, but once you figure it out, you can reverse engineer EVERY brand's feed chart to collect a consensus on what is safe. If you have chelated micros, you can make concentrates, and metallic sulfates you'll need to weigh out each before use, unless you buy a premixed blend such as STEM. Metallic sulfates are good so long as they're not used to make a concentrate.

What environment do you grow in? Do you use vpd? Measure dli? You definately know what you're talking about, but I see guys running 100watts of led trying to use the same recipes as someone using 1k watta, and not understanding that everything is proportional to the growing environment. What would you say the perfect ratios for a near perfect environment would be?

i'm running Jack's RO at the moment. 12-4-16. start to finish. no additives except a bit of epsom at end of bloom for the sulfur

Actually it's not my P, it's a clone of Jack's 10-30-20 formula. The numbers off to the right.

The micro details in the sheet may not be accurate. It's packaged premixed TM-7 that I'm using for micros. Is STEM a better alternative for micros?

I just use the angelfire calc for reverse engineering.

Ace Hardware has Hi-Yield calcium nitrate 4lbs for $8. I'm trying Jack's 12-4-16 right now in veg at 3 weeks from seed 1.2 EC then I'll use the 5-12-26 in flower.
