looks like Mg on some leaves. if you run 321 vs 3part in a nute calculator, i wonder what the ppm of Mg is in each one?
@TintEastwood usually has all these common formulas on hand.
Jacks.
My coco grows always do better with PH around 6.2.

Running 5.8 often resulted in Mg defs. I made it worse by adding more - too much- Mg.

I start with RO water.

I for one am done with Jack's.
Same here. I'm filling my first res of flora trio tomorrow. To experiment I'll keep my other res of jack's then I'm gonna run half the garden with jack's 321 and the other half with GH flora trio for 1 res fill. If there's no difference between the jack's plants versus the gh plants I know my problems aren't related to my fertilizer. I wind burned the shit out of them with a ULV fogger that I returned. Worst thing I've done to my plants in years. Live and learn.

To be fair to jack's I had no problems with my plants last cycle at all. None. So maybe I'm being a little tough on them. I've had problems this grow cycle that had nothing to do with jack's and I think I'm just generally pissed off and jack's might possibly be my scapegoat. I wind burned my plants with a junk ULV fogger that took them a week to recover from. When they were in veg I used horticultural soap and neem oil that burned the foliage and new growth coming out for nearly a week afterwards. In the trash those bottles went. I'll run my side by side until my res is empty then I'll see if there's any difference in the lushness of the jack's plants versus the gh plants.

Switching to all LED has had a hell of a learning curve too. I've never flowered with all LED before and the last cycle was great but I ran into a few issues. I hit the plants at full blast with the lights too early while under feeding at 600ppm resulting in multiple deficiencies that had nothing to do with my fertilizer, but had a lot to do with operator error on my part. If the plants look the same after the 1 res side by side test I'll have confirmation the issues I'm having aren't fertilizer related at all.

I'll report back with results and a couple pics next week.

Edited :)

WTF??? I thought it was bye bye forever? Now you're missing the simplicity of good results? Oh johnnywishywash, say it ain't so. 28 pages down the drain. I have never even tried Jacks 321 because it sounded too complicated from the start. I never want to screw around weighing nutes. Welcome back to the KISS side.

Read my edit. I'll report back if the jack's is going bye bye or not. And I do miss the simplicity of my maxi bloom. It was easy.

I think I might have jumped the gun on my jack's criticism. I sprayed venerage cg last night and lowered the power on my lights. This morning they all have a lushness to them they did not have yesterday. I notice every time I spray the stuff the plants just seem to perk right up the next day. Great product. They seem to be recovering from the damage I caused beautifully. It clearly had nothing to do with the jack's in my situation. I'm only feeding 1 plant the flora trio for my experiment at this point. I'll snap some pictures. I'm pretty hard on myself so the slightest imperfection in my foliage stresses me out.

I raised my ph on the GH trio to 6.2 last night.
I'm seriously considering dumping the rez today and making a mix of Jack's @ 1.8ec/6.2ph and seeing what happens.

I'd be soooo happy if things cleared up.
Jack's has been easy to use and I still have another 25lbs. bag of 5-12-26 I'd like to use up.

I'll swap it out today, give it a go for a week and see what happens.

I hope it works out for you.

Just a few days into flower and....

I made no changes to the feed so I'm stumped. Issues with mobile nutrients, but they're so different between the plants its hard to nail down the cause.
The tops look great still, but I don't want to push the issues any further.
View attachment 5014094
I've been doing some research and have found others say they've had the same issues with Jack's. They love it, but can never seem to get dialed in on it.

For now I'm going back to the GH trio following their new schedule @ 1.2ec with another .2ec of Calimagic. I'm going to try floating around there for now @ 1.4 total and see how things progress. Possibly bump up to 1.7 if I see issues.

I am really frustrated though that Jack's isn't working out....
When it is working it makes some pretty plants.
Is there any chance nutrient solution could have made contact with those couple of damaged leaves? The rest of them look phenomenal. Keep us posted on how things progress. I'd yank those leaves and ride out 7 days to see if it was a fluke or not. Great looking plants. Always love seeing your setup.

Pics of the whole garden after the venerate spray. Perked everything up nicely. I'll post back here in a few days with more pics to see if I got this train back on the tracks. If I can just stop spraying stupid shit on my plants. I will never use neem or hortucultural soap ever again. All those tree hugging hippie pesticides just mangled my plants. End of diatribe :)

I believe there are better organic solutions that work for cannabis. Citric acid, azagaurd, venerate, and spinosad rock and are all relatively inexpensive except for azagaurd.

I can't emphasize enough how badly I fucked these little plants up. They're finally recovering from all my abuse. Kinda can't even believe it. I almost chucked em all last week. One is still real sad looking but has good new growth coming out....slowly :)

I just wanted to drop in to say I definitely rushed to judgment on the jack's. I needed to increase my ppm. For my situation 1.8-1.85 ec is the sweet spot. Less causes deficiencies in even modest sized plants. One of my plants was only about 3 1/2' tall. Quite bushy though and she developed beginning signs of a calcium deficiency as did several other plants due to my under feeding. I read on a jack's enthusiast thread over at icmag and got some bad info and ran with it. Many people claimed you could run 600ppm start to finish. I tried it. Ruined my last flower cycle doing it. I didn't realize the damage I was causing by unintentionally starving them until it was too late. I corrected it in week 3 of flower, but they had already been stunted and suffered some heavy foliage damage, so it definitely diminished yield. If I had just left my ec where I had been running it I wouldn't have had any issues. All plants get the same strength from clone through flower. No issues.

I'll snap some more pics later and report back. I'm a little disappointed with myself for rushing to judgment considering all the success I've had running 321 over the last few flower cycles. I hope my operator error doesn't inhibit anyone from trying jack's.

Also, I'd suggest omitting the epsom salt until flower. Jack's is loaded with mag. I noticed tip burn on vegging plants until I stopped adding the epsom to my res. As soon as I hit flower I add the epsom.

I have been doing this with great success so far.
Typically omitting epsom salt works great for me. I recently switched to all LED and for the first time in nearly 5 years I'm seeing a mag deficiency. I added the epsom at the recommended dosage to my res. Only 2 plants are affected so far. The rest of them are fine. Hopefully this adjustment gets the train back on the tracks. As many people as are using LED these days I thought it important to share my observation hoping it may help other LED gardeners encountering the same problem.

Ive been running Jacks @ the 3-2-1 ratio on my current grow of Ethos Genetics Candy Store R1 all the way through veg and the plants look awesome. Some of the fan leaves are huge! I switched over to 12/12 a couple days ago and changed out my res to their bloom 10-30-20 and so far they still look awesome. Im really liking Jacks so far. Planning on keeping them on the bloom nutes for another week then switching back to the 5-12-26. I'll be upping the EC some once they are flowering good. I had some deficiencies last run by not upping the EC.

Beautifully lush plants sir. I'm glad to hear some positive feedback about the 10-30-20. I'll be trying it for the first time this cycle. It seems like the mix is perfect for that burst of new foliage and flower sites consuming a lot of N, P, and K.

I'm glad you posted your experience with the 321. I had some deficiencies last cycle too due to running at a low ppm for the first 3 weeks. This time I've gone up to 1.8-1.85 ec for a smooth run. It's good to know I'm not the only one trying to find the sweet spot on ec. I had been a big believer in not using epsom salt in veg, but this cycle with the all LED conversion I began having a mag deficiency showing on 2 plants. I'll add the epsom to the res moving forward keeping the total strength at 1.8-1.85 ec. Other than the mag deficiency the plants look great. I'll report back in a few days.

One last thing to add I just remembered. The first time I ran jack's 321 a few years back I had a mag deficiency. I started adding the epsom salt for the rest of that grow and never had an issue through harvest. Maybe my issue isn't at all tied to the LED conversion but plain old operator error not following instructions. When I started using 321 again this past year I was thinking the "less is more" is a good idea after hearing others omit the epsom with positive results. I was wrong and so were they. Don't monkey with the jack's. JR Peters recommends it for a reason :)

So it seems like you increased the strength by about a third. Good to know. I'll be keeping an eye on my next time with Jack's. So many people, myself included, sometimes lean a little toward starving the girls because we are afraid of filling them up with too many chemicals and screwing up the finished product. But sometimes it is the opposite.

A past quote from Renfro that had me rollin...


"Every grow is different but I can't even count how many times I have seen growers that are on the weak sauce train, so worried about feeding too strong, ending up with deficiencies and all they had to do to correct it is raise the PPM."

Late to the convo. Hai!

Yeah something changed with GH Flora's formulation recently. I've used RO water, coco as the medium, and Micro + Bloom, PH always came out to about 5.8 -6.0. Talking years, here. Now, a PH of 5.2 with the last two 1 gal bottle purchases, and yellow leaves.

It was simplicity of GH that got me into using it. Now, giving it up. It feels like a breakup!
