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

[Huckster79]

Tough to say but initially I would use a diluted solution entirely. If it still persists, then drop the calcinit a few ppm. Less work for you until you figure it out...

Thats what 51% of my gut says, the 49% said do one feeding of just the jacks no calnit...

I think ill do a half values one and go from there as i think i have a light eater on my hands

 

[samiam]

I'm just started supplementing with 2 grams of biomin calcium powder and dropped my calcite down to 1 gram after the stretch. So far working great.

Im new to jacks, real happy so far! I have two twins of gg4, one in a basic ppk rig another in breathable container of coco and One gg4 and bubba cush cross in breathable coco container, shes much larger than other two, same age roughly she was from seed and much more vigerous. Flipped em 1/1/18 I fed crazy light in veg trying to keep her from growing me out of room. First feed in flower was 370ppm of 5-12-26 and added calnit to about 600ppm. The gg4 rocking it my bubba glue got N claw bad almost immediately. I fed her a straight water with heavy run off, shes perking right back up. My question now is to water down the whole mix for her or just back down the calnit?

I have fed 50+ strains straight Jacks' 3-2-1 from fresh out of the cloner all the way through harvest. If you're feeding that low I sincerely doubt it's the nitrogen toxicity claw. I have found if the coco gets dry AT ALL deficiencies will pop up quick. Have you kept the coco wet at all times? I'm talking watering 2-10 times per day.

I don't water that quite that frequently but never have, but I don't let it go dry like promix or soil, but without any issue before. I too find it odd with all the folks that use it flawlessly in addition to how lightly I feed in both veg and flower an overfed situation doens't make sense really...

I really had to bend and pinch the hell out of this one right before the flip to make sure hight constraints for stretch were okay, I'm wondering if she didn't get long enough to recover, I gave her most of a week on water only and veg cycle lighting. Maybe should have given her a bit more time...

I think I'll mark it up as quark, and just keep my eye on her as I bring her back up on nutes.

it doesn't make sense cause nitrogen isn't what makes the leaves claw

IMO if you aren't watering coco at LEAST 2x per day you aren't getting close to unlocking its potential. I believe that one of the big advantages of coco is that it drains very very well, so it's virtually impossible to over water once roots are established. Oxygen is delivered to the root zone via water, so the more often you can water the more you can supercharge the root zone with 02.

Every single time I've ever had an issue in coco (and I've had my share of issues) the solution has always been more frequent watering. If coco gets dry at all, the salts begin concentrating and the pH begins swinging wildly.

Totally agree.

The other side of this is that a pot properly sized for multiple daily feedings will be insufficient for once a day watering. A well developed root system will take more than you can supply in a single watering. Means you're introducing dry coir problems every day. The commonly held wisdom that coir pots generally need to be smaller than soil pots may assume multiple feeds per day.

I can get a healthy plant through harvest in a five gallon pot with one watering a day. 2 gallon pots, that eventually get to 1 feeding per hour, significantly out yield the 5 gallons, once per day feeding, growing the same plant.

Not being a smart ass, but then what is "nitrogen claw"?

 

[p0opstlnksal0t]

Are any of you guys using Humic or Fulvic acid as a PH Down? Also how many of you are adding silica to your Jacks/nute regimen?

I think i agree...though its not been my past or entirely current process. Im expirimenting right now i have one girl on a ppk, passive plant killer, set up. Its a non accurate name but thats what they call it. The plant can wick nutes up from a bottom res, and every two hours its getting a top water pumped from that res. That girl is rocking.... so prob next round gunna do em all that style...

 

[MrBungle]

I personally think the clawing has to do with environment more so than Nitrogen. tried lowering N, bumping Mg, adjusting micros... My SSH would still claw... it wasn't until I switched from my old box to an expanded open room, that I observed my SSH to not claw...

 

[samiam]

I just switched over from using Coco to rock wool mini cubes. The growth is a little faster with rw and Soooo much easier on my back.

Same rules apply in rw. Start in small pots, 4" square pot, 1, 2, 5 than 7 gal before flip of course that would be for a 2 month veg with alot of topping and plenty of light in veg.

It's best to invest in a high pressure pump and timer if your using rw, or Coco as to take advantage of multiple waterings.

Okay. Just ran a fresh new batch of water/nutes and used ppm(500 scale) this time to measure. Went 360ppm Jacks, 120ppm Epsom Salt, 240ppm cal/nit and ph is 6.0. If this doesn't work I'm throwing in the towel and going back to AN.

 

[samiam]

Don't let your Coco dry out too much. And don't start in to big a pot. Keep your lights on and off temps close. Move your lights up if you see problems in the top of plants, than lower it a little each day till your plants get use to the light.

 

[Rabbi]

I don't use coco, I run aeroponics. I'm hoping the addition of Epsom salt will help my yellowing issues out.

 

[bsgospel]

So here is the issue then- adsorbtion. Aeroponics and hydroponics will feature different results as a result of movement and conductivity. Are we talking a mist or fog?

Though, I think, regardless: Jacks has always been tried and true in a physical medium. With adsorbtion. I would hate for the system to get a bad rap/give you bad results as a function of (root vs. medium) vs. (root vs. oxygen/non-substrate)

The set up works perfectly fine with AN. I'm hoping between measuring with ppm this time and adding Epsom that it takes care of my issues. Soon find out.

 

[bsgospel]

Welp there is a difference in AN vs. Jack's. If AN in aeroponics is your bag- Groovy. Aeroponics with Jack's might not be the same. AN/concentrate liquid vs. Jacks/dry (albeit dissolved)- this would be the variable I focus in on...I hope it proves out. Not disparaging at all. Please do report!

Thx man shall do.

AN does work well for me but the cost comparison between the 2 is what attracts me to Jacks. Plus it seems like everyone except me is having great success with Jacks so that obviously tells me it's on my end somewhere. I'll plug away at it for a bit. AN is such a rip-off price wise that it motivates me to hammer things out with Jacks. I'll for sure report back.

I myself am experimenting with jacks in an 8 kilowatt drain to waste Coco set up. If you read Delta 9 exes posts you will see you don't need the Epsom salt I am running equal volume Jacks to c a l c i n i t at 1.2 EC. I was watering once a day in 4 gallon pots the Coco was drying way too fast and I had salt build-ups immediately. I have switched to 2 watering per day to see if it helps. This is only temporary so that I get dry Cycles to fill the pots with roots once this happens I will be watering every hour or two
