Been using Jack 5-12-26 in the 3:2:1 ratio for a while now and very happy. I just chopped a Blueberry Muffin that was grown start to finish with Jacks. I grew the same cut out back in the Spring, but switched to Jacks during that run.
This time around, using Jacks, silica, and fulvic, yields are up, the buds are harder, the terps are stronger. The first run was great smoke, and this is even better. Thirty five days veg, fifty six of flower and the result is 3 quart jars and 1 pint jar.
So far, Jacks is looking like it will be my base for the foreseeable future. (y)

Realistically, I consider my nutrient costs to be almost zero if expressed in cost per ounce of dried flower.

Maybe $15-20 a year for Jacks and CalNit, $2 or $3 for MgSO4. Less than $20/year for fulvic, same for silica, maybe $10 for PH down. Add another $30 or $40/year for switching out dead SILs and maybe $100 worth of coco/perlite/hydroton/containers and I grow for next to nothing. (pulling these numbers out of the air, but they can't be far off)

It blows my mind when I think of what I used to spend a year on cannabis far inferior to what I now grow.

Great to see another convert lol the stuff really does work great, I use it with a liquid silica product and recharge once a week, same results stanky dense nugs with a cost that most growers laugh at. I seriously have been shit on by 2 local growers for using such a cheap product but ill take the Pepsi challenge with them any day??? I'm gonna try the flower schedule greengenes is running this round and see if I notice a difference hes the one who turned me onto it and I never looked back

When I tell someone about my setup, I usually start with "I do everything wrong".:oops:;)

So much of what I do goes against the old school stoner science and I DGAF because the results speak for themselves.?

Hey guys,
I recently started Jack's 321 full strength with some clones I picked up. I've had nothing but issues with lockout and defenciencies appearing on leaves. Was full strength to much to start clones off at? I went off greengenes YouTube advice. Open to recommendations on how to reset this grow as I'm currently stressing the fuck out over the way my plants are looking. Do I need to flush? 20211101_214608.jpg 20211101_214635.jpg

I'm not familiar with GreenGene so could use some more details. Is that coco with clay pebbles? Why the clay pebbles? How often are you feeding? What's the pH of your nutrient mix?

A good dry out and watering with plain h2o works wonders. I'm no expert. So wait for smarter people.

I'm running canna in one table and cyco coco in the other as a comparison. Cyco is the one with the clay obviously. First few waterings were around 6.0-6.1 than last two were around 5.8. I just flushed straight RO water through both tables. Run off PPM was around 1600 or 3.2Ec. The Table that's looking the worst is all After party. Cake strains seem to be doing better.

I'm sure you know that's extremely high numbers, especially for run off. You might want to flush again.

I have been feeding 2.0-2.2 EC from seed to harvest, just like GreenGenes. He doesn't talk about pH much but it needs to be in range for sure. I'm guessing that the Coco could of used some rinsing before hand. Hopefully you'll get on top of it.

Live an learn. These coco products come advertised as PhD and buffered. You think you're saving time by not rinsing. Seem to be better off buying the cheap stuff mother earth ect. And doing in yourself.

Are you running full strength seed to harvest?

If the coco was doo doo it will take a week or so to level out the media, 1600 runoff is a ton I run jacks at about 900 to 1000 max and only had an issue with burn when my rh was too low, how much dry back are you getting??? If its a lot between waterings I'd lower the ppms to about 700 and feed 2 times a day, flush then go a bit heavier on the cal nit to try and knock some of the other salts out of the medium, a foliar feed or 2 or 3 with Epsom will show you if the coco is gobbling it up as well, and when you say full strength are you meaning 321 or 3.6 2.4 1.2 ???

And gg is usually in the jacks recommended range of 5.8 to 6.2 i should add i stay at 5.8 to 6.0 from the looks of those pics the coco may just need to level out, bennies in a healthy dose along with some fulvic or humic will also help chelate some of the salts the coco is storing and get some of it into the plants at the same time, id give em some time and keep em moist coco is hard to overwater especially with added aeration

Yes full strength as you listed. That being said I think it was just way to much to start clones out at with an unestablished root zone in 3 gallon pots. Should have started half strength and let the root system buildup/stretch out to accommodate stronger feeds. I got the Run Off to 700-750PPM after 2 flushes of straight RO water. No Watering today. Will start tomorrow at 80% Strength which is exactly 321 . I believe not Flushing and PH'ing the COCO although it was top of the line shit caused a lot of my issues.

You are running Jacks at 3.6 2.4 1.2?

Once you get it on the right track, you'll just know by the look. Especially in a hydroponic set up because of how quick the plants respond to changes. Jack's is really good and it'll get you there. I personally only check runoff if I am at a loss or fairly deep into troubleshooting. But, it's definitely an option when shit is going sideways and will help you paint a clearer picture of actual problems.

I started at the 321 ratio and pushed it up over time. Always a good idea with something new not to go full strength until you build an understanding. I feel like I'm getting these cal/mag deficiencies under LEDs and started with trying a bit more of the CalNit (part b) which burnt the tips a little and I then I raised the epsoms and that help stabilize the mix some. Its an interesting product because of how its balance which plays off of the other parts. I feel the science when I use it. ?
