[SLYNINJA]

Please help

I see you like your cannabis well done?
Turn you out put down.
Yikes,
What was that stupid Smash Mouth song from the 90s I know you know the one I’m about walking on a sun or some shit what’s your lights height and setting?

 

[Captspaulding]

And dude, there’s absolutely no way that happened in 24 hours. Can I see a picture from last week? I know you got some.?

 

[TheGoldenRoad]

It normally takes a lot longer than 24 hours for leaves to cook like that… those are toasty.

Im using AC infinity EVO6 Led's with the Samsung LM301H EVO diodes cranked up to 100% height is 10 inches from highest tops 1300 ppm co2

Everything was running mint then this happened in less than 24hrs so I don't think it'd be lights

 

[TheGoldenRoad]

I don’t run co2 but 100% intensity @ 10 inches is no bueno even for a 100 watt light. And it looks like your light just stock without any modifications is rated at 500 watts.

 

[TheGoldenRoad]

I have twin 150 watt led panels and have them set to 80% I’m 18” off the canopy and 745 ppfd.

Bro, you should do what I said, but it’s all good man you do you.im a sweet baby rays guy when it comes to bbq sauce.
Get something you really enjoy for this delicious bbq spread.
I’m not the type of dude to comment on stuff if I don’t have a 99.9999999% surity of what I’m saying.
And again, I’ll say that didn’t happen in 24 hours, dude if that’s the case, you had a fire in an adjacent building connected to yours or something right because your heat spiked and your proximity is grilling them

 

[Eledin]

Lets supose most of the damage happened in 24 hours even if they were looking a bit rough before. 10 inches for that light I agree, youre roasting them 100%, but also you might have burned them with bad PH or excessive nutrients, did you check both of those? Any temperature or humidity spike?
One clear sign of the roasting is the praying leaves besides all the crunchyness.
Sometimes they pray because theyre happy and want more light sometimes they pray for their lives, literally. When the heat is too much they pray to decrease surface leaf temperature unlike when theyre happy and wanna reach for more light.

 

[Eledin]

Upon further inspection I can see clear signs of clawing in lower leaves because of nitrogen toxicity. I think you have 2 problems going on, lights WAY too close as mentioned by our friends and high ppm, when youre going hydro like that you need to be very careful and sometimes you need to read your plants FAST because the recommended dosage might be too much or too little depending on the consistency of the genetics in the seeds. If its clones you know most of them are gonna eat similar but if theyre not each seed can be different. If you go from seed, stable genetics are more expensive but in my opinion is worth spending more if youre not getting ripped off and its trully stabilized with good phenos.

If you come to the forums and "keep it real" you get more help! Many of Us are lifelong growers on this Forum! This to many of Us looks like 1st time grower mistake(s). Diagnosis= Lighting Heat Burn/ Nutrient Burn/ the whole system is unbalanced (plant and rhizome)

1st sign of stress "Always back off Light Pressure"!

1)right now you need to raise the light to 30"inches 40% Power...
2)fill those RW Cubes full water but only1/2 feed strength ....

When you "force them to work" under high light/heat conditions, high ppm co2, - they pull too much water and nutrient - they are both Sun Burnt and Nutrient Burnt. Your forcing them to process water at 4 times the rate and they nutrient burn, are you following?

"In cool temps we water less and feed more - In high temps we water more feed less " - are you following?
(both conditions, High/Low Temps can be managed)

Facts.
They do both, rh usually factors in on that.
Example
Pic 1
The medium is too wet. Light is too close causing the leaves to curl inward to hide from the output/poximity of the lighting
Pic 2
Way to hot and dry of a climate.
Pic 3 way to hot/close and way to high rh. And a slight n tox is creeping in.
Just trying to help,
Chop and el both know thier stuff as well.
I will say, its ok to make mistakes, we have all been there, most onset issues in cannabis have outward signs and damage atrributed to most issues that take some time to get to were you are.
No judgement here, just solid growers that know whats good.
We didnt just fall off the ol turnip truck.

Looks like they were done with the stretch not long ago too, that might have added to the symptoms of too much light and heat intensifying quickly. If theyre stunted theyre also not gonna eat as usual, so even if you were going with the same dosage they might have burned. I see theyre all equally affected which leads me to think that either most of the damage is because of the light or they are clones so they all got burnt by the lights and nutes.

What @Captspaulding and @Choppr said is very true. Follow the advice of these guys and you’ll see a new dimension to growing.

Also,
Currerntly at the capts hq
On the moon
Peep how far my lights are from that canopy.
I wejt and took these just for you hermano.
30-36 inches above canopy.
Im at 75% outputoldests plants are endnof week7

Do you run yours that high all cycle?

 

[Captspaulding]

Do you run yours that high all cycle?

Yep, and my plants are never stretched out the only time that I not running as high as possible is when I’m doing a stacked rig, you know the over under set up that I like to do from time to time then headroom does become an issue, especially with sativa But I still generally will prune the fuck out of them and keep them pretty low

Right on. By the fall cycle I’m going to upgrade my lighting to be able to put out the beams necessary at that height. Lower light, lower footprint.

It’s no surprises me from time to time with certain cultivars that bitch inordinately with some of these newer light panels man I finished runs at 45% output like you know 30 to 36 inches above canopy but then again I’ve also blasted my fair share of strains trying to stress test them for breeding purposes and I’ll drop lights all over them dude on the sides on the top and I’ll blast them full blast at 10 fucking inches to see what they can handle And if they can handle that then I know when people get my beans that they’re gonna have to fucking commit to a war with their own plants in order to mess them up somehow, with a bred out strain of coarse.
