I think it really depends on your preference. The 1 part tap and RO formula are great. Simple. Effective. And dirt cheap. What the 3-2-1 system provides is supreme flexibility. Do you have a strain that's requiring much more calcium than your average strain? Increase the calcium nitrate. Problem solved. Want to decrease nitrogen towards flower? Decrease the calcium nitrate. Increase the 5-12-26. Have a strain that doesn't need much magnesium sulfate? Omit the epsom salt. Jack's 5-12-26 already has 6.3% magnesium sulfate. Some growers don't ever add the epsom salt to the 3-2-1 system. Without getting into the weeds jack's 5-12-26 is versatile, flexible, soluble, stable, consistent and great for any strain for these reasons if you're running a hydroponic system.

I'm planning to order the RO formula to test it out. There is no magnesium sulfate in the mix. Instead they use magnesium nitrate. I want to email jack's to find out if I can add epsom salt if needed. Other than that concern everything else looked right as rain to me on the ingredients and ratios and I would have no aversion to ordering it with confidence. I would recommend anyone to please buy the 25# bags instead of those smaller packs. Jack's is only cheap if you're buying it in the big bags. If you buy the small bags you're paying as much as a General Hydroponics product. I got a 5 gallon homer bucket with a gasket lid from home depot and toss my whole 25# bag right in there. I buy my epsom salt from walmart. Nobody else is cheaper. Equate brand. I get my calcium nitrate off of Amazon from PowerGrow. Dirt cheap.

Jack's is still cheaper. GH wants you to buy florapro grow, florapro bloom,and their calcium / magnesium mix.

Flora pro grow: $57 for 25# @ grow green
Flora pro bloom: $58 for 25# @ grow green
Calcium magnesium: $50 for 25# @ grow green (out of stock)
57+58+50= $165 + shipping

Jack's 5-12-26 25#: $36.48 for 25# @ grow green
Calcium nitrate: $50 for 25# @ amazon
Epsom salt: $5 for 4# @ walmart
36.48+50+5= $91.48 + shipping.

Any other questions? :)

I recently switched from Canna to Mega Crop, but you all are convincing me to go Jacks.

I use the both versions. Following the recommended nutrient schedules both recipes include Epsom salts.

Thanks for hooking up a link to the feed chart. That makes the RO formula all the more appealing providing flexibility with being able to increase the magnesium sulfate. Do you prefer one formula over the other for any reason? I just recently started running the 3-2-1 with 5-12-26 at full strength with much better results than I experienced at a reduced EC.

I like both equally to be honest. I like to use the ro version during veg because its simpler since it is 2 parts. I like to use the 3-2-1 version in flower because it offers more flexibility to tailor to specific needs during the different stages of flower production.

I took the plunge 3 days ago and transitioned my entire garden over to jack's 5-12-26 from GH's maxi grow / bloom, and all of the plants look fantastic at 647-675PPM! That's pretty incredible to me, and explains why my jack's grown flowers taste and burn better. I have to feed GH's maxi grow / bloom at 775-825PPM to prevent deficiencies. Jack's gets the job done at nearly 200PPM less. The plants are growing and are as happy as they can be with significantly less fertilizer input, so the plants are absorbing lower levels of elements and I believe this is directly related to flavor and burn qualities.

We've all smoked one of those fertilizer over loaded hydro flowers that scorch your throat and lungs. They often burn poorly, but visually appear like any other high quality flower. I believe it's the plant simply absorbing too many elements. Those elements accumulate in the plant's tissue. Flowers for instance, right? Who on earth wants an excessive amount of phosphorous or potassium in their flowers? P&K loaded flowers look great. It's all downhill from there. The flowers taste terrible, and they burn poorly due to the excess elements present in the plant tissue. That problem doesn't occur with jack's. I'm excited to post my post harvest quality report on the latest jack's grown flowers in the near future. Anyone else notice their flowers taste better with jack's versus other fertilizers that require much higher PPM's to satisfy the plant's needs?

Lights out at the moment. I'll snap pics and post them later tonight. I hate when I see a thread like this and the OP doesn't post pics. Just pisses me off :)

Here is a great interview from a huge organic gardening proponent talking to one of the developers of Jack’s. I’m very much about soil and organics but I might try it sometime as she (the Jack’s person) makes very good points and stresses that you don’t need lots of nutrients for them to work, and explains the science behind their methods. Even Tad Hussey, the interviewer seems happy to hear about their work and that they try to work with traditional methods to find a balance between “organic” and “chemical” cultivation.

The idea that we should "push" the ppms instead of using the minimum amount necessary to keep them happy is what makes for nasty bud-you see it all the time, pics of buds with fried leaves everywhere. That's one reason I like coco so much, you can get away with much lower #s and just feed more often.

There’s guys who will tell you if fan leaves don’t have blanched tips you’re not trying hard enough. Lol.

I've been running Jacks for a bit, and happy with it. Stuff is cheap as chips. My additives (Si, Fulvic, and Kelp) are the expensive part of my feed, not Jack's base nutes. I use cheap CalNit and Epsom Salts.

How does this work? I for example I know phosphorus is obvious a used for the ATP molecule and it makes the phosphate backbone for DNA and other essential plant stuff, but apart from what is being used, how is this unused phosphorus being stored and in what form. If there's too much iron in the soil will your plant take that up even if it doesn't need it, and then what. Not only that but aren't all the elements in some other form. For example you don't say that you put chlorine on your food because it's bound up with sodium.

I know that they used hemp plants @ Chernobyl to clean up all those heavy metals from the ground . I guess it's the best plant for them to do this with. Honestly know a whole lot about it but it's very interesting and I'm learning more everyday . :bigjoint:

mine was the version 1.0 had horrible pH drops with it in a stand-alone res. they couldn't figure it out either.
