A question for the growers using Jacks 5-12-26

[Budley Doright]

I have been using jacks for maybe the last year....

I had been mixing it.....44 gallons at a time.....

When I mixed my stock solution..... with 880g of jacks....

It was a little weaker than my mix....

I upped the jacks to 920 and multiplied by .66 to come up with how much calcium nitrate....about what my old ppms were.....

The moral of the story.... you can adjust the ppm/ec by adjusting the amount of jacks up or down..... then multiplying that by .66 to come up with the proper ratio of calcium nitrate....

I must admit.... the stock solution is much cooler...and more accurate....once you get what you want......

I found when making stock solution that the 880 grams per gallon of Jack's was right on but 590 grams of calnit did not equal out right. I found I needed 10ml's of jacks solution and about 12.5 of the calnit to hit my 1/.67 levels.

Beyond that, I find that just the two products work fine for me, no need for extra Mg. My last run With Karma's OG hit 25% thc so the resin is definitely there.

600 ppm is 360 ppm jacks and 240 ppm calcinit 240/360=.67

750 ppm is 450 ppm jacks and 300 ppm calcinit 300/450=.67

900 ppm is 540 ppm jacks and 360 ppm calcinit 360/540=.67

delta posted this earlier in the thread..




My next batch I will look at the ppms of each component is......

These fertilizer products will absorb water from the air....

which can cause some ppm issues in theory....

finally had to put in a re-order. My one lb of jack's lasted almost 5 years, jesus h. christ time flies. Price has gone up and they no longer sell single lbs.

in 2010 1 lb = $5, 2015 its 4 lbs for $30.

good times

Hey Folk,
What an amazing thread. I'm making the switch from 3 part GH/AN nutrients to running Jack'd Pro Hydro and Calnit. The system I'm running is Rockwool cubes on top of slabs in leach trays, drain to waste, closed system w/Co2 and A/C. Does the 1 to .67 ratio still hold true and what EC should I be shooting for during transition - same questions for flowering.

Oh, and I appreciate the simplicity of adding Jack's to a given ppm, then adding Calnit to bring the ppms up to strength, but how do I do it when I already have some nutrients in the tank. I.E. My 200 gallon res gets down to 10 or 15 gallons, I top off with RO water and I have a diluted solution that I'm trying to bring up to full strength.........

Cheers all,

Im not a big fan of that method when Im going to be using the same amount all the time....

I would empty your res.... then add jacks .... until you hit your mark......but weigh it....

then do the same ting with cal nitrate..... weigh it......

I use a smaller res.... but I did this...then make 10 bags....


now I just dump a bag of each in...... and ppm when Im done mixing....

I use....550-600 all the way through...

Just ordered some jacks. Switching from h3ads 6/9.

Thanks for the great info.

Wish I did not just buy that last G of flora bloom...

Cheers

if u don't have enough micro to use it up, u can use it as a boost at .2ec added to ur base nutrient. also u can use it up like head did at the end of flower where he cut the micro n just ran bloom. just a couple ideas for ya bud.

Heya dlcain - i noticed u said jacks pro hydro which is 16-4-17 but not sure if u are aware we usually mean jacks hdroponic which is 5-12-26. So the formula is different.

Peace brother

Jack’s Hydro FeED is specifically designed to be used as a one bag, complete hydroponic nutrient system. Calcium and magnesium are provided in the bendable nitrate form. Effectively, this one bag will substitute for the older two-part hydroponic formulas.

This innovative formula provides all the macro, secondary and micronutrients in a one-part system. Hydro FeED was designed specially for hydroponically grown basil, cilantro, chives, parsley, lettuce and most vegetables. Includes a proprietary blend of iron chelates that keeps iron available even as the pH varies up to a high of 8.0. Also contains a significant level of soluble calcium and magnesium, for an all-around plant nutrition.



========================================================

Well jacks comes out with a one part mix....

I would do the stuff....

 

[Budley Doright]

ack’s Professional 16-4-17 Hydro FeED is our new one bag blend. This innovative fertilizer supplies all macro, secondary, and micro nutrients essential to plant growth. It is designed for growing herbs like basil, chives, and parsley, as well as lettuces, spinach and other greens. We have found though that it is great for other vegetables as well. The greatest part of this fertilizer is that all the nutrients are available to a pH of 8, so you won’t have to worry about nutrient lock out at higher pHs.


For a small amount mixing, you can simply put 1 teaspoon in 1 gallon of water. For 10 gallons of finished solution, add 1.27 ounces per 10 gallons. This will give you 150ppm of Nitrogen.

In 10 gallons of water, dissolve 1.3 ounces of 5-12-26, when that is totally dissolved add 1 tablespoon of Epsom salts for extra Magnesium and Sulfur. Finally add in .86 ounces of Calcium Nitrate. This will give you 150ppm of Nitrogen, which is the perfect rate for growing hydroponically.

If Im not mistaken..... they are the same cost for 25#

but the new formulation eliminates the calcium nitrate...


Did jacks just get quite a bit cheaper????

will it work well with coco? Seeing as how H & G is a bitch to get right now seems like a good time to swtich...

The one number that jumps out is phos..quite different than 5-12-26

The 5-12-26 + Calcium Nitrate is a great vegetative fertilizer if you need to modify your nitrogen needs or to fit in with your specific water types. This combo can be used to grow a wide range of crops from lettuces, herbs, and fruiting crops.


fruiting crops...... i thing that other hydro forumula is too low in phos for cannabis...

so 5-12-26 + calnit 1:.67 is still the jam for coco??

 

[Budley Doright]

I think so .... I thought they had replaced the old standby...

But its for growing lettuce ...not cannabis... IMO

I have not read this whole thread as I am about to begin digging into it but thought for the "hell of it" i would post here the question I am trying to answer as I am totally new to mixing salts. I recently switched to an injection system in which I am mixing my nutes 50x concentrated and injecting a 2% ratio into my irrigation system going to my plants. To save money on not having multiple dosatrons. Will Jacks hydroponic special with the calcium nitrate hold stable when mixed 50x strength? Or will elements seperate and fall out of solution? I would aerate the solution or recirculate it id either would help. In this all in one mix I am also including the PH up or down adjustment I would need to het my water to the appropriate PH.... as it truely is an all in one mix.... thats it tho... base and the appropriate amount of ph up or down. I am using well water and not RO. My well water is at 150ppm and ph of 7. Anyone have and tips or any information to help answer the question of will this hold in solution? I tried maxibloom and something falls outta solution after a few hours no matter is I recirculate, aerate, or let sit... like a milky white powder. almost like baking soda. maybe those with more experience with raw salts and mixing nutes can help me as I am new to this. I have always been a user of bottled nutes but want to move away from that and am trying to take my first baby steps in learning! Thanks!!

If you mix the jacks 5-12-26 with the calcium nitrate in your stock solution you will precipitate calcium sulfate out of solution. This is most likely what is happening in your maxibloom.

Thank you so much!!! So if my well water hAs enough calcium and sulphur in it then it should not even matter! Gott get a breKdown of my base well water done... Any recomendations on where to do that? Im in the upper peninsula of MI! No mans land!

If your well has calcium and sulfur in it it will be spitting out gypsum. I doubt that is happening. The reason you have two solutions of nutrients is to keep the sulfur away from the calcium. The two together create the precipitate and prevent the two from being dissolved in solution. In small enough quantities the two dont bump into each other enough to have favorable collisions that cause precipitation to occur.

The jacks 5-12-26 has the sulfur and the calcium nitrate has the calcium. It is cheaper to have the micro nutrients teamed up with sulfur than a chelating agent.
This is why you need to keep the two apart till your final solution

I dont know where to test the well water at.
