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

Found the post. This is a copy/paste of said recipe I follow for stock solution

You weigh out 880 grams of Jacks 5-12-26 for one jug and then ~ 580 grams of Jacks Calcnit for the other jug.

Then it is 10ml each per gallon of RO water to mix feed at 600PPM (500 scale), 5ml each for 300PPM. easy peasy lemon squeegee or something along those lines.

A gallon stock jug should mix about 375 gallons of RO water.

Don't know my PH and by all accounts here on icmag, if you use RO water, you never need to bother checking PH.

I use the stock solution formula, 10ml/gal each, start to finish and the results are great. Being this is my first grow, all I can say is if they were better, I wouldn't know how to contain myself with the results. The Jacks is very, very impressive. Also I run at about 600ppm as well. Plants seem to love it, with no bad signs. Well no bad signs with nutrients. My GSC did fall over, so I really wish I had built a scrog for it. I will find the link for the stock solution formula and post it for you as well. Also I didn't use any additives or "Magic" juice. Just Jacks and PH up/down, and R/O water.

thanks briz,
yea im gonna try it at 600ppm for now and see how it goes.. I actually just switched from ppm to EC to make things easier for me and the help i receive from this site. I'm running [email protected] which is 2.7 EC comprised of N+ plus H&G Coco for veg outdoors at the moment plus my custom AACT. Point being is im wondering if im gonna need to raise my EC of the Jacks/Calnit more than 600ppm to avoid a Def. or would 600-1000ppm of Jacks/Calnit be enough to keep my babies healthy in veg and feasting like they are right now..
Which leads me to my other question, is it better to stick to the Jacks/Calnit or drop both and switch to Jack Bloom 10-30-20- since i'm running high on the EC as of right now... I'm just scared of adding too much N when in flower... But Thank you again for that Stock solution link.. I'll prolly make a batch and test it out on some other greens until my H&G is all gone.

Addendum, ive gone to mixing 1 and 2 quart batches to keep the stock fresh. Takes a loooong time to use up a gallon of stock and the 5 12 26 can get some kind of nasty slime on the top if it sits too long. Had a batch do that so started mixing less.

My ro ph is 5.8-5.9 and around 5.4-5.6 after mix. I use SM90 which brings the ph back to about 5.8 and buffers it a bit

Anyone on the west coast who hates paying shipping as much as I do might want to check out grow more's new 5-11-26 hydro formula from their new Mendocino dry WSF mixes. It's pretty much the same as jacks. It has added carbs too. Smells like cotton candy.

i have been reading a few threads on jacks for a few weeks now, happened to be at grow more picking up order for a buddy's hydro shop and there was a pallet of it right at the front door basically calling my name.So I grabbed a bag. Funny tho, No calnit at grow more . But found it easily at a local farm supply.

BeardedCocoNut, would you care to share a pic of the grow more 5-11-26 guaranteed analysis from the label, including the derived from section?

thanks.

Here's the pic of the guaranteed analysis of the grow more hydro formula. Hopefully I'm doing this right. I don't post often.

I cut back on the cal nit after stretch and cut it out completely at the end of week 4. It helps the budding accelerate faster and improves the calyx-leaf ratio.

a question about the 12-12 phase...

ok so what i am doing is when stretch is over, start decreasing the canclinit, until at week 4 its not being used.

i've been feeding at EC 1.2 (600 PPM - 360PPm jacks and 240 PPM camcinit at .5) all along, so once calcinit is decreased and then cut out, the EC will be significantly lower

do i just keep feeding the jacks at 320 PPM between week 4 and flush?

do i increase it?

if increase is the answer by how much, or do i increases until i see that its too high, then back off

searched this thread, and could not find an answer, so the implication seems to be just cut the calcinit, and keep jacks PPM the same as it was before cutting calcinit

What medium are you in Raven?

I have increased my dose of jack in week 4, only to hit that .8-1.0 ec mark...

Last run, I added a bit more of jacks and an mpk booster with b vitamins to finish the remaining ec...

Whats everyone else doing around the last weeks? And in what medium! Thanks...

wow i forgot an important detail,

50/50 doc/perlite in 10 Liter hemp buckets

i am loving the results on my first jacks grow. just entered 12-12 week 4

I personally wait until the last 10 days to cut the ca/nit. I keep my jacks ppm normal and that cut in ppm's from the ca/nit missing contributes to the flush cycle since we are lowering the overall ppms. During the last week I lower the jacks ppm's as needed based on the plants feeding pattern. Thats my method.

Run both cal nit and jacks until week 6-7 at least. I add more jacks and less cal nit as bloom progresses and stay at 1.2-1.4 ec throughout flower.

Been alternating that with Jack's Blossom Booster and been having great results.

Has anyone had better results pouring the powder directly into their tanks VS. the premixed stock solution?

Been using the premixed for over a year with solid results, but have been thinking about dumping the powder in directly instead after reading some old posts...

Pros/Cons?

I do 44 gallons at a whack....

I use the correct amount for 44 gallons.....and use a gallon contrainer to dissolve in......

I likes it better me thinks....

I do powder... Jack's first, dump it in while filling rez... fill rez to 1/2 or 3/4 full wait 5-10 minutes (do something else, maintenance etc.) hit the rez with my hose again to agitate the Jacks then dump in the Cal-Nit... it dissolves a lot easier.

Couldn't be easier.

Im a wondrin' the same thing waxi. Ive had issues with precipitation and ive always used stock. Have had stock go bad with crap forming in the fert solution too. Switched to mixing qt batches from gal stock batches to address the gunk.

I still get precipitation from my mixed nute solution. I use a rodi 5 stage filter too. 0 PPM ph5.9 source water

Anyone venture a guess what this precipitate is in the bottom

I was doing the larger batches.....

I decided to use the 2 parts as a powder....

So I had to determine how many grams of each to do 44 gallons....

Then measure them both.....

I use a measuring cup....

I like using the intermediate container to dissolve and break any lumps.

I use a wide mouth jar and a dowel to stir and squish any lumps....

At the end I check to make sure that ppm is within range....


I have no plans to go back to stock solution....
 
Hey Folks,

Where is everyone getting their Jack's and CalNit from these days? I'm ready to buy some for my new grow. Don't plan to use any other nutrient but may use drip clean. Thanks
