A question for the growers using Jacks 5-12-26
- Thread starter Jabapc
- Start date
I used 5-11-26 mendo for 2 runs and they were my highest yielding runs. Due to the organic additives in it its not as PH stable as jacks is but its still great. It smells EXACTLY like chocolate whey protein shake mix. My only issue with it was the decreased amount of magnesium compared to jacks.
In my opinion, jacks/calnit and a little citric acid/sugar is all that is needed for create a bad ass product.
I start out at 250ppm jacks/ 250ppm calnit then move up to 300/300. Then flip still at 300/300 and a week in I go to 450 jacks/300 calnit and then slope down to 360 jacks/ 240 calnit. Last week before flush I would drop the calnit and just run 360-450 jacks and flush for 10 days. Work well for me
Ditto....Little sm90 just before flip and first week or so of flower (mostly for the wetting agent).
Couple small shots of Age Old Humic watered in by hand for a few weeks, not in the res. Humic is a great chelator, but the organics can make my res slightly unstable. Same with molases, not in the res, sparingly l hand watered..coulpe weeks mid to later flower.
I have been making a combined stock solution, 3000ppm jacks to 2000ppmCalnit, and adding that to any given voulme of water to hit my desired ppm. That doser looks like it could work well with a one part like that.
As far as the humic, sm90 and molases, they aren't hurting anything..but are they helping, maybe? The PPK guys dont use them and they know Jacks.
....For everything there is a season....

I recently bought some 5-12-26 Jacks to replace my 5-11-26 Chem-Gro and I was running into a K def before. But still after a week with the Jacks plants are still deficient and im chasing the feed. Seems like nothing is enough.
I set Sunday morning at 1.7EC and Tuesday night its already at 1.4EC with only a gallon uptake.
I've posted about this before in the past with a different strain and got told it was nutrient burn, but I disagreed as the feed was dropping and was only 1.0EC and added more 5-11-26 to a 3:2 ratio to CaNO3 and upped the feed to 1.4EC and that fixed it.
I guess my question is can something with my tap precipitate with the 5-12-26 and cause the potassium to be stripped giving an illusion that EC is dropping? Or do I just need to kick it up? Its already at 1.7EC.

Anyone have any advice?
I upped them last night to 1.9EC at 950ppm.
Ive never gone over 1.6EC before. This is strange.

Purpling i,actually noticed recently.
These pics are from when I was feeding with an,old stock at 1.4EC
I had this issue before and posted about it here and was told nute burn. This was at 0.8EC for a foot tall veg DWC plant. I upped the nutes and added more 5-11-26(old stock I was using before I got jacks, very similar except less Mg) and this turned the issue around.

My symptoms that led me to K def were stretching, brittle stems(snapped a few duringLST which never happens as im gentle) yellow tips that spread to margins and curled tips.
This is more apparent on new growth which K def I read happens on old growth. This coupled with the feed drops led me to deficiency.

This was in the past. Which i really do believe I was underfeeding as feeding more fixed it.
Now I was feeding low and got this issue and increased and keep increasing yet the issue persists.
Im not 100% sure its def which is why im here asking questions.
If i am,overfeeding why is nutrient strength dropping 300ppm over 2.5 days?
Which specific element is dropping 300ppm? All of them equally?
Overabundance of certain elements will cause others to be unavailable to the plant. For example, nitrogen will always be taken if its available. Is it taking in calcium as part of that 300ppm? If your nutes are too high, you will kill the little root tips that take in calcium. And that's just one scenario.
Just because 300ppm is coming out of your solution doesn't mean it's being used properly... Or at all.

Hard to tell what made up that ppm drop. I misquoted ot was 150ppm drop 0.3EC
Roots look healthy. Nice fuzzy white hairs on the roots above water level.
So youre saying I should cut back and change the ratio of 5-12-26 to CaNO3?

So what excess causes K to,not be taken up?

Only thing i read too much P and too much NA can cause k def.
Nitrogen, magnesium, sodium.
Most likely nitrogen.
What you should do with jacks is calculate what it takes to get 100-150 ppms of nitrogen in your mix. That's a good place to start. Calculate off of the nitrogen and everything else should be in proper concentration. Again, more factors into that, but that's a good reference point.
At 2.0ec you're feeding 400ppms of N alone.
I think it's 5% N in the hydro and 15% N Calnit right?

Im feeding 305ppm of CaNO3 which is 15.5% N and 19% Ca I think.
460ppm of 5-12-26
My tap,is 90ppm
How do i figure out how much ppm of each element with the percentages?

General Hydroponic growing with 2 part
Jack’s Professional Hydroponic Formula has been designed to serve as a base foundation for hydroponic growing. It can be manipulated in such a manner as to provide virtually any combination of nutrient levels desired, providing the highest availability to plants, due primarily to Jack’s proven ability to remain in true solution over long periods of time.
Jack’s Professional 5-12-26 Hydroponic
Follow these steps to obtain a precipitate free solution
Dissolve 130 ounces of 5-12-26 Hydroponic in 1000 gallons of final feed solution. You will obtain the following elemental PPM concentrations:
Element N P K Mg SO4 Fe Mn Zn Cu B Mo
PPM 50 52 215 63 246 3 .50 .15 .15 .50 .10
For the most effective use of the Hydroponic formula, it is essential that the nutrient content of the irrigation water being used is known. These figures are then taken into consideration and should be added to the distilled water figures as quotes above. This is of special importance when figuring the need for adding more Magnesium (Mg) and Calcium (ca) depending on the needs of the crops being grown.
Dissolve any additional Epsom salts desired into the above 1000-gallon solution before proceeding. For most crops, 50 PPM Magnesium is an adequate level in solution. To increase your Magnesium levels, dissolve 10 ounces of Epsom salts in 1000-gallons of final feed solution to obtain 7.5 PPM additional Magnesium and 3.00 ppm Sulfur (SO4).
IT IS ESSENTIAL THAT ANY EPSOM SALTS TO BE ADDED MUST BE ADDED TO THE HYDROPONIC SOLUTION AND BE DISSOLVED BEFORE THE ADDITION OF CALCIUM NITRATE.
NOTE: Jack’s Hydroponic fertilizer contains NO calcium.
After dissolving Jack’s Hydroponic and any Epsom salts in the tank, proceed as follows:
Dissolve 86 ounces of Calcium Nitrate into the above 1000-gallon solution to obtain a total nutrient concentration of 150 PPM Nitrogen and 116 PPM Calcium.
Should higher Nitrogen and Potassium levels be desired, the addition of 1-ounce Potassium Nitrate per 1000 gallons will add the following concentrations:
Nitrogen—1.00 ppm N Potassium 2.74 ppm K
Should higher Calcium levels be desired, the addition of 1 ounce Calcium Chloride per 1000-gallons would add the following concentrations:
Calcium as Ca—2.09 ppm Ca
Should higher Potash levels be desired, the addition of 1 ounce Potassium Sulfate per 1000-gallons would add the following concentrations:
Potassium as K—3.11 ppm K
Should higher Manganese levels be desired, the addition of 1-ounce Manganese sulfate per 1000 gallons would add the following concentrations:
Manganese as Mn—1.87 ppm Mn
Should higher Iron levels be desired, the addition of 1 ounce of the following per 1000 gallons will add the following concentrations:
13% Chelated Iron as Fe EDTA — 0.975 ppm Fe
11% Chelated Iron as Fe DTPA — 0.80 ppm Fe
6% Chelated Iron as Fe EDDHA — 0.45 ppm Fe
Jack’s Hydroponic Formula is heavily buffered to produce an idea working solution pH of between 6.00 and 6.50, but under unusual circumstances, it may be necessary to adjust the solution pH up or down with the use of mineral or organic acid complexes. Please consult water quality when choosing amount for pH change.
