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

[dr-dank]

I had problems with jacks having to much K when i did 1:.67 and even when I switched over to 3jacks 1 mag 2 calnit. It for sure was causing some lockout. Only when I did 2.5g Jacks 0.5g mag 2.5g calnit did it start to be the winning mix for me.
Comes out N 136 , P 35, K 146, Ca 125, Mg 55, S 71.5.
Ive been using that from start to finish and everything looks great.
. . .

I ran cannastats and got same numbers. I mixed up a batch and it was about 800 PPM on the .5 scale once phed to 5.8. Gave the girls a drench last night and will see how this works for them.

Ok great. Good luck man, I hope its the winning mix for you.
Let me know how it goes for you. The plants seem to stay fully green start to finish with this mix and are accompanied by great yields.

Thanks! I will report back. I will likely dilute down to 600 ppm as that is what I have been using with the 6/9 h3ad formula.

I should do another side by side.

link me in when u start it

@ terror.

I have started the transition. Adds to my 5G elevated res are now your mix @ 600 PPMs. Not sure I have room/time for a side by side.

I can say I recently added a citrus sap to closet, and it was showing some deficiency under 6/9. Looked like mag. I use bluemats but went ahead and manually drenched the gals with your mix. The citrus seems to have greened up.

So far no harm and seems to have helped.

Thanks

never heard of citrus sap before, but that looks like a winning cross.
I hear bluemats are great It just worry about relying on them to function.

Too me 6/9 is low on a few things, including nitrogen especially if you have co2, open hoods/gavitas.

I picked up the genetics at harborside in San Jose. Seems to be sativa dominant given the stretch. I believe they said it was a gorilla glue cross. I have been growing Sly OG for over a year now, and interesting to see the same 6/9 behave differently across strains. The proverbial mag whore or whatnot...

The BMs are working out. I don't rely on them for anything except using less water and for making less work. I do feel that the no runoff eventually gives me salt build up, hence I run around 500-600 PPM in the res and do a manual DTW flush once a week.

It was about the time I went to BMs that I also switched to jacks at the 1:67 ratio. That is what prompted my side by side where I hand watered two plants, one with 6/9 the other jacks, to see if it was jacks or BMs. The 6/9 did fine while the jacks (@ 1:67) plant showed issues.

Interesting you say not enough N in 6/9. Some mention cutting out the N in later flower, but I believe you said you use the higher N of jacks at 1:1 + mag/sulfate all the way through. I have been doing 6/9 up until flush.

Best regards

Ya seems to be a gg cross.

Yes It just doesn't make sense to me to let them fade out that much and whenever I run near 100ppm N they don't seem as healthy.

Thinking about switching to coco and Jack's hydro/Cal Nit.
My tap water comes in at 150ppm,and 7.5 ph.I'd rather not get a RO system if i don't have to.Do you guys think I'll have problems using plain tap water??

 

[AWDTERROR]

You could probably get by with it but I would seriously advise R.o.
It didn't like my 300ppm tap and it still didn't like it when I did 1/2R.o 1/2tap and that was 150ppm.

I've been using it in veg on and off for a while with fine results.

My tap is 130 to 140 ppm. I use the 1 : .67 ratio with 210ppm of Jacks and 140ppm of calnit. For a reading of 480ppm total including the 130ppm of my tap water.

Thats a good number for charging fresh batches of coco and new transpants. I dilute down to about 430ppm if things are getting too green.

At 150ppm it's worth a shot just using your tap.

Maybe i can send them a sample of my water like some other members suggested??

Sounds very simple.Do you throw the jacks first and let it dissolve then add the calnit?How easy does it dissolve?In my case i'll be using a 55 gallon drum to mix.

 

[caljim]

Hookah79...I'm mixing into a 40 gallon res. Jacks 1st , then calnit. They both take their time dissolving into solution. I use a pump to stir everything and allow about 20 minutes for each part to fully dissolve.

Making stock solutions is on my list of to dos. They would save a lot of time mixing and help me to stop over shooting the calnit number.

Hope that helps.

 

[AWDTERROR]

Sending in a sample of your tap water is a good start. I just don't like that at least in my area, the water is different ppm throughout the year. So I never really know what i'm getting. I personally didn't like 1/.67 but it works great for a lot of people. My sativas loved it but my ogs did not.

Calcium nitrate will be super simple to dissolve. The jacks can have problems not completely dissolving leaving behind very small amounts of sediment at the bottom of the container, it also takes a minute compared to calnit. If you decide to ad magnesium sulfate that will mix pretty fast too. Gentle agitation and hopefully some warm water and it wont be hard for you.

 

[Hookah79]

Thank you caljim and terror.
On a side not,would it be an issue if i flushed my plants before flip and started using jack's instead of the current nutes i am using??The medium is promix hp.

 

[AWDTERROR]

ive never used promix but I switched from bottled nutrients to jacks in flower and everything went great. I even hit between 2.49-2.66 per light that run.

Hey man I have a trick that works great, think I might have read it on here but can't remember. I bought an oil funnel and keep a 32oz Powerade bottle right next to my rez which is like 40 gallons or so. I use the funnel to dump the Jacks in and then fill it up 2/3 with water then shake the shit out of it for 30 seconds or so, dump it in the rez then repeat with CalNit. Never had any issues getting everything dissolved quickly and it saves the time of waiting for it to swirl around and dissolve in the rez. Hope that helps

LMAO that's too funny man,i just noticed your reply ,and this is what i've been doing (kind of)for the past couple of weeks.

I let the air stones bubble in the rez for a while,then i measure the jacks with a scale ,pour the dry nutes in (no funnel),fill up the gatorade bottles 1/2-2/3 with rez water,shake ,then pour back in rez.IMHO i believe this has to be one of the easiest ways.

I tried the way Delta advised me to do,using my meter to hit a certain ppm range ,but wasn't successful.You can't really get an accurate ppm reading unless your nutes are fully dissolved ,which is time consuming when using a 55 gal rez.

Waxy u gonna use jacks in your fertigation mixing your own stock?

 

[caljim]

Question for those of you making stock solutions.

Has any one experienced this?......Black crusty ring that forms at the top of solution and clings tenaciously to the sides of the container.

I'm adding 1 gallon of distilled water to 880 grams of 5-12-26 and shake shake shake. The solutions are made in well washed Heinz vinegar bottles. I hate to toss them, but Im a tv repair man, not a chemist.

Thanks for your input.
