I'm not saying he has one. I'm questioning what he meant. Or are you implying there is no such thing? You've no qualifier to your statement. If you are saying LED lighting does not cause these issues then I might agree with supporting evidence.

Having a "Cal/mag" issue is nonsense just as much as the led defeciency statement.

"the multitude of defficencies" sounds like a medium issue, not a lighting issue. As long as the light is providing proper spectrum, then the medium is to be suspect for not retaining or properly releasing the nutrients.

You in Coco?

Yup, its a real term used to define the multitude of defficencies many strains will experience under white led in CoCo if one has not made the necessary adjustments. He's just now switching over from hps so he's best to learn this stuff now before experiencing Huge losses like i & many others have.
Even the local Grow Stores that are just now getting hip to led supply free Mag-Amp with every Fluence, Gavita or white led purchase. They discuss the Real Thing LedDefficiency at the stores & recognize it for what it is.
If you're in soil, chances are you're good already.

I don't really take pics anymore. In coco I just go Jack's 321 from clone to harvest in 5 gal pots if I ever have an issue a little Epsom or a pH adjust fixes it I've never had to use Cal/mag
having not used Jack's, does it contain calcium and magnesium? Do you use tap water or RO?

Now It looks like these are at end of life? I would experience this look when flushing. I suppose you don't flush in living soil..

Well, technically none as this is a seed tent now, but the genetics I use and grow in living soil made this under that LED rig. The first pic is round 2 for seed and the bottom pic was my first attempt at flowering after using it to veg for my outdoors.

Wow! THANK YOU VERY MUCH!!!!
@OneHitDone & i were discussing this topic as being the main suspect to why i was having led prob but w/o the terms & knowledge you just linked. He actually brought it up & suggested my K levels being to high in my nutes after being added to what's already in CoCo. Funny cuz prior to him saying this i was under the false impression that CoCo was as neutral as it gets & that the plants will only be getting what i feed them. But also noticed the ppms/ec of my fresh CoCo over the yrs & wondered why???
Never even took into consideration CeC. Now this explains the missing link in my journey to defeating LedDefficiency once n for all.
Thanks Pop22 & OHD for being on the right path.
Are you the one that said to soak the new CoCo in 1700 ppm's of cal-mag for 24hrs before using it?
1700 is allot (500 scale i assume). Have you actually done this?
So the leds are using so much nutes & the k in coco is preventing many of them from uptaking? That leads to lock out in a "multitude" of ways. Mag & Phos being some of the most noticable, but is actually everything to some degree..
Oh man now you got me all worked up & ill have to watch the following video on "Why We like Coco so much".
Thats why sooooooo many CoCo users are failing under led. And why soil growers thrive-on the majority level anyways.
Why the Fuck don't the led manufacturers tell us this????

Led have higher output so the plants need more nutes I wouldn't call that an "led defeciency" if you went from cfl to hps you would have the same problem if you didn't change the nutes. At the end of the day a defeciency is the growers fault not the lights.

Honestly you and like 1 other person are the only people that have had problems that I have seen. While hundreds maybe even thousands of people don't have any issues that's why I wouldn't call it an "led defeciency" if the majority of people do just fine with led you can't blame the lights.

I use tap it uses calcium nitrate and magnesium sulfate it's a much better combo vs Cal/mag imo. I've seen tons of people that have issues using Cal/mag I've never seen anyone have issues using Jack's or just using some Epsom salt instead of Cal/mag. My first couple grows I did liquid feed with Cal/mag it never turned out as good as Jack's or living soil but I also got better at growing so maybe that played a bigger role than nutes. None of us are scientist so there's really no way to know what's best

Personally, I've found a soil/coco blend to be an effective medium. I'd always found coco to be problematic. I've been using a 70/30 soil/coco blend for a couple years now and find that all the fussy PH and nutrient issues of coco are gone, and that I'm using less nutrients to achieve the same results. Not saying this is the best way, just that it has worked very well for me. I do think its a better conbination than soil/perlite.

Bingo! That's the answer I was thinking you were meaning.

And thus why I use Megacrop 2.0, it seems to have just the right blend and I've not had the problems I've seen with every other nutrient I've tried. Hell I grew organic for a long time rather than deal with nutrient control issues. And I like simple, which I found in Megacrop. From what I've read, Jack's seems to be quite similar, and I've heard a lot of good about it. Beats the hell out of being sucked into using 47 different bottles of snake oil...lol!

Now you know why all those people using PK boosters in coco have so much trouble!

Agreed! Soil/coco and megacrop 2.0, with 4x 4k/5k qb120s and 2 30w bars.

Day 12 of flower. The lemon og hit the ground running lol its getting massive whereas all else has just begun. Also have a pepper plant in there a couple seedlings and a runt my friend gave me. Trying to defoliate early this pull as week 3 seems late with the amount of foliage ive been producing but nonetheless no deficiencies.

Go search coco grows under led & tell me what your honest stats are.
Led have higher output so the plants need more nutes I wouldn't call that an "led defeciency" if you went from cfl to hps you would have the same problem if you didn't change the nutes. At the end of the day a defeciency is the growers fault not the lights.
I 100% disagree. I used to use floro/Mh/Hps & never had to make adjustments for any of those lights.
At first i thought maybe we should take this discussion elsewhere, then it occurred, what better place then a white led thread.
Ive used several types of lighting. Led is the only one that requires such adjustments thus far.
The high k i. Coco never influenced my grows in a neg way before switching to white led. The majority of mine are enhanced so i have the problem less then when i use plain white.
Oh, i beg to differ. Its the majority of new led users that haven't yet figured it out that are suffering . Especially those in CoCo which is what the majority of big cultivars use it seams.
I did tell you that the local growstores hand out free Mag with every white led purchase right?
So what about growing in Peet or Pro-Mix?
