@hybridway2 K, Mn, Zn, Mg and S is what I seem to have to add for my grows. Lol so everything *shrug* I've evolved to using sulphates instead of phosphates or nitrates for my supplemental additives. Potassium sulphate over potassium phosphate/potassium nitrate, Zinc sulphate, Manganese Sulphate, Epsom. Attempting to control ingredients without effecting ratios of other base nutes and I like the additional S. By the looks of this graphic it seems like it could be S possibly, and maybe why my addition of K2SO4 helped when I added it? Have you tried Epsom yet?

No, Coco is not a nightmare, and nether do LED's produce deficient plants.

I'd guess K. This vid describes what I mean by K looking like Ca-Mg or other shit first.. It's what led me to add K2SO4 when I did, because the leafs were discolored they were hotter and so raising my light helped keep the scorching too a lesser degree. I tried to keep the leaf temp under 85 and added K2SO4 with some Ca-Mg and epsom and the green came back.

This is what a tent full of K deficiency, or Ca locking out K, looks like.. Lol
(2/14)..
1/23 - All's quiet on the western front...
2/14 - Symptoms have progressed and I've added K2SO4, Ca-Mg, and epsom, notice how yellow the leaves...
2/26 - Green had started to come back just before chop lol what a bitch
... anyway, you can see how bad they got, in the close up those leaves used to be crispy and dry without any green..
I'm an outdoor and HPS grower that switched to LED out of curiosity. I haven't run into deficiencies like this before. This was my first QB run. I think backing off the light helped too. It was hard posting these embarrassing pics but hopefully it can add to the solution lol

You are running co2? Doesn't that speed up and make defencies that much worse faster?This is what a tent full of K deficiency, or Ca locking out K, looks like.. Lol

1. Good luck with your lights @MeGaKiLlErMaN.
2. There's no such thing as led deficiencies.
3. Coco is so fucking easy to grow in.
4. People need to man up and stop blaming their tools.

Mostly 3500k Citizen and Cree cobs. My "hand me down" tent has a mix of 3000 and 3500k Crees, and a pair of old Area 51 RW-75s.

I'm not sure what it is, but something I've noticed is that I pretty much only see LED guys get on here with issues. Barely ever have I seen a CMH or HPS or T5HO thread describing these common deficiencies. Do you think it's because most LED growers are new growers? Is that what's happening? Do you not think SPD as any part to play in a plants response? Just curious, I've liked many of your pics, you got great grows, keep it up!
Have to agree on this one.
I guess I stepped up to QB (from E27 my first LED experience) and DWC at the same time. So my learning curve was a little steep for my background. Ill hit you up @jarvild

That’s an en-lightened response that seems more likely than not to be true.Leds causing deficiencies. ive herd it all now.

I believe the issue is starting to become the "Quality" of coco.
A decade and a half ago when it wasn't cool and only commercial tomato growers were using it, the brick coco would expand to nice long fibered goodness.
Coco I have tried recently when expanded is short pith particles that look like they've been run through a grinder.
I suspect the increased demand has lowered quality and the companies buying and selling at higher prices are getting the A grade materials.
To me personally it has pushed coco back out of my grow game as it doesn't seem the value it once was

Once i got my temps and humidity where they needed to be in my space the growing pains of moving from hps to led stopped. All the phantom deficiencies and chasing my own tail stopped. Now they just grow how there supposed to unless i make a grower error. I was trying to keep my temps and rh where i always had with hps and the plants were not pleased. All of the problems being discusse here were present. Upped my ambient temps about 5 degrees and a mild bump in rh..... boom. Everything stabilized. Just my experience.

So let's just cut to the chase. Back in the hps days a grower might go to the grow shop and walk out with this equipment to be up and running:
Hps Fixture
Exhaust Fan
Thermostat
Soil
Nutrients
(possible dehumidifier)
(Co2 optional)
Led Grower gonna need:
Led Fixture
Environmental Controller
Heater
Exhaust Fan
Dehumidifier
Soil
Nutrients
(possible Co2 mandatory if temps too cool to exchange air)

fun thread here
fine with it except am "offended" by
the word "toxic..oh come on bro..thats a snowflake word now
and my big peeve..saying "day-tah".
i figured Ozzies in the testing machone video would know better..
mcgilliebro..cool idea ..but maybe you should start small and finance it yourself

I am in a way. I'm making the prototype now. We will see though. I'm getting messages daily about it but I don't expect the first campaign to hit record numbers, most people want to buy after they see a working model which is fair. Especially after talking about the 600W for $600 option.
