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

[Roperunner420]

Okay guys newbie in the game, 3 rounds under my belt with emerald harvest. Boy did that get old, so now I'm week 2 with three different bodhi strains. ( hit a couple ruff spots with the winter on N.E.) ordered jacks, cal nit, and Epsom salts, mixed it as the screenshot I posted. Came out to like 1050ppm at (.5 scale). I diluted to 750ppm recommend fed it to the veg tent for 2 two days in 2gal pure coco (handwater for now). Perked them up nicely. Threw caution to the wind and fed the jacks to the 12 in flower and sure enough they look fantastic. Started super cropping under the gavita and two 400s in the 4x8. So my question is.... what's the best way to proceed after stretch with the cal nit? I'd rather not use a bloom booster but I guess I could foliar a little something before the sites get swollen. Would love to hear some guidance on this. I can get pics when the lights turn on. (Had to screenshot my pic to get it sized to upload) thanks guys.

Since your in coir, I suggest keeping the cal nit in the mix till your ready for straight water. I switch to water around the 10 day from harvest mark. I get low ppm run off within a couple days of switching. Its all dependent on your environment and watering frequency. Some people like to cut the cal nit maybe another 10 days before that. but I caution to not cut it too early, cause coir needs the correct cec to keep nutrient uptake happening, otherwise you will stall bud formation with an unbalanced medium. I also suggest not to foliar, especially indoors in flower.


If your looking for a pk boost, try your base nutrient at 1ec, 500ppm plus whatever pk you choose at .2ec. around week 5 to 6 of a 8 to 9 week strain. It works quite well with minimum risk of nutrient burn or damage.

Do you guys have any advice for switching to Jacks 3-2-1. Currently using Botanicare, are any supplements recommended, calmag, silica blast? How about making concentrates and using dosing pumps, Do-able? I have the dosing pumps.

This thread already covers all of your questions in great detail.

Thanks.

Reading 1000+ posts to find one bit of info is a PITA. Replies which state or insinuate, "Search, you lazy dumbass", are absolutely zero help and are very off-putting to most people who see a comment like that. What goes through my dumb-ass mind when I read that is... (insert expletives here). IMO, when questions are common, a sticky should be made with the most often asked questions and is only editable and can only be added to by the OP and/or a Moderator. Or... how about just answering the damn question or don't post anything?

As the homie said.. your answers are all here..
but my advice is simply.. do it, your pockets will thank you.

No supplements necessary, and as with anything, I always recommend trying the base first, and building after that. I recommend homies skip the epsom unless the plants want it. I did a mag hungry run (gg4) without any epsom, and would do it the same way again

Cal-mag I say no.. its simply cal nit + epsom.. you can add more or less of those if ya need to down the line.

I have used silica, and i have not used silica (both 99% Si and potassium silicate via agil).. I haven't done a side by side to have a strong opion.. but I like the numbers with a little extra K, and I like the health benefits of Si.

Concentrates are well documented here.. And will work for your dosers.... I don't like them personally.. Concentrate info is documented throughout thread.

I dabble with enzymes. I believe in em.. I use highly concentrated barley enzyme for ponds.

I'd like to trust drip clean a bit more.. but I don't know enough about it and don't use it consistently.

I recently been hand watering microbial organic stuff (sea green) every so often with the base. My impression is that the plants benefit.

some use jacks/ Calnit only, some add epsom, i myself am adding a little agsil and fulvic to the mix

I'm with you.. but that would require someone to do it lol.

There are ways of cutting the bullshit out by filtering user posts i believe.

My opinion is that there is more than one way to skin a cat. I like to read about all the ways, pick up a gem or two along the way, and have the voice of repetition hammer info into my brain.
It will be clear what the accepted best practices are.

Having read this thread in it's entirety, as well as others including DJM's thread, Coco DTW thread, KISS thread, Rykus, etc, It is generally worth reading them front to back.

I think it is important to understand the whys behind the hows.

I copy and paste into word documents based on topics and threads.

I will also say that once tunnel vision kicks in and avatars become recognizable, the bullshit will fade away, and you will breeze thru the threads

I agree, Trich. However, old coots like me often have short-term memory issues. Add ADD to the mix and 'stoopit' people like me are nearly hopeless. So we geezers need "Cliff's Notes" versions of "Cannabis Growing for Dummies".

You can grow top notch, high yields, with just jacks and cal nit. 6% of the mix is mg, that's about the highest % mg in any hydro based nutrient that ive seen, so mg is definitely not needed.




I make concentrates at the rate of 880g jacks per gallon jug, and 580g cal nit per gallon jug. 10ml of each makes around 1.3ec total. But the jacks does leave a sludge in the concentrate jug at that strength, so next time im going to use 440g jacks, and use 20ml per gallon.

Wow... that's so EASY!! I might switch to Jack's and Cal Nit when my current nutes are gone.

 

[p0opstlnksal0t]

also remember 3 part jacks and 2 part calnit can be measured in volume of equal amounts equaling their correct dosing ratio.... 3 teaspoons of Jacks Hydro and 3 teaspoons of Calnit would give you the correct 3 to 2 ratio. although i measure by EC now days its just so much easier...

my current run i have like 7 strains altogether. only one of them showed Mg. def. issues. the GG4 which just so happened to make up half of my room! haha

Excellent advice!! Thanks guys. Searched, looking, read a bunch of pages, miles of stuff I don't care about at this point. I know there's plenty of good people and knowledge here. Glad you guys showed up.

TT, Awesome man! I usually do several strains in one grow. GG4 is one of them. I don't really know jack about nutes. I got started with a recipe, it worked good and I rolled with it. Looking back, a ton of $$ went out....

Start without epsom, how do you know that you need it? What's the deficiency? On the concentrates, do you need to keep them separate until mixing in the reservoir? Is there a max level ppm not to exceed? How about flushing mid bloom to get rid of build up in coco?

Again, thanks! Good people.

Very punny.. it's worth getting to know nutrients a little.

You'll get mag deficiency.. which can be a result of, of course mag deficiency, but also could be from lockout. Yellowing between veins is what it will end up as. Red stems can be indicative, as can upturned leaf serrations. GG4 leaves will twist when she wants mag.
Its one of the easiest deficiency to detect, and also misdiagnose.
Almost every time I get mag def. in my garden it is simply being locked out.

Concentrates are kept separate.

feed light, and you don't need to flush..
it works, but it won't work if your not on ur game.

if your coco dries, salts will crystallize, build, and nutrients will get locked out.
so your options are: keep it moist ALWAYS and/or allow for decent runoff.

I only "flush" my coco in veg because i don't allow for runoff.. so I feed about 1.1.. then a couple rounds of .6, which is usually when I'll add some fun stuff - microbes, enzymes, etc. Then a full feed, etc.
I can do that for about 2 weeks before i sense a need for some decent runoff.

coco is a funny media, but as DHF says, you gotta know the rules.

 

[p0opstlnksal0t]

i dont do concentrate myself so i dont know about mixing that up. i mix all my shit in a 300g tote about once a week and it gets fed @ 1.2ec now dtw in pure coco. ive lowered my epsom from 3-2-1 to about 3-2-.5 ratio and if i do see any def. in my gg4's now ill foliar spray epsom at about .4-.5ec this cured my first deficiency in my gg4 when i wasnt using any epsom in the feed.

Good stuff. Very much appreciated.

A couple more things good to mention are that cal nit absorbs moisture. Its good to seal it up. I use buckets with the gamma lids for easy access. But that could mess up your ratios if going by weight.


If mg is needed like tt explained, its likely a water frequency problem, or environmental problem not allowing uptake of mg. that's why people add mg, its a band aid for not having something else dialed in. Sometimes it works, sometimes it doesn't, cause you still haven't diagnosed the actual problem of why your not having enough mg when the mix is at the top of the industry for % mg. Sometimes it throws off your ratio of elements when adding mg, and it locks out other things, then your just chasing your tail on def and tox. Better to understand that your base nutrient has everything it needs, so tackle the problem from the water frequency or vpd, or cold root zone, or pests, or ph.


Also I think tt explained the flush scenario mid flower pretty well. Just keep an eye on r.o. ec. I try to follow djm's advice which is check the ro ec with a small amount of extra feed, and if its above 800 ppm or 1.6ec flush it below with your base feed of 1 to 1.2ec. try not to let the medium reach over 900ppm before switching to water for final leaching and harvest.


Funny how the plant can adapt. Ive got a friend that feeds up to 2500ppm, and does ok. But the bud quality of smoke is poor comparatively to lower feed that I use.


Don't overthink the extra stuff too much. Master the base nutrient, then become your own mad scientist with other tests of amendments. Djm hits 1.2 plus on the regular with this simple nutrient strategy. HR hits 2 plus with this base nutrient strategy. And im not talking just jacks here. take your pick, any cannabis based nute should work well. Jacks is just one of the most economical ways to get the base nutrients our plants need.

Another direction to come from.

I always had a hard time getting my ec stable enough to be sure I was adding the right amount of calnit to jacks hydro to achieve the desired ratio.

And my tap water makes a jacks stock solution cling to the side of the container with precipitation.

So, what I do....is fill a 5gal with tap.

add 100 grams Jacks hydro....then add(for veg) 82grams calnit.. To make a one part stock solution that gets diluted to my desired EC.

Flower gets a descending amount of calnit, starting at 80% (of jacks weight) and coming down to 65% by the start of the third week of flower.

Low and slow at 1.0 to 1.2 ec, heading to the low side as flower
progresses. Flinish with low ec feed... .2ec

By making a concentrated one part and measuring by %weight (with dry salts) I get the ratio I, and the plants, want. Every time.

Would work great with dosers also. Your ph up/down could be added to the mix to run on a single doser.

Different strokes for different folks.

This is a HUGE mistake. Nutrients like Jacks are sold as two separate parts for a reason. If you combine them together at concentration they will react with each other and your nutrients will precipitate out of solution, making them unavailable to your plant.

Never ever ever combine concentrated nutrient solutions. Mix each into the rez at working strength before adding the next.
