Possible LED light burn

[Ghostwriter31]

Ok so to troubleshoot any possible problems from the beginning. I’m using super soil in bottom 2/3 almost. 40% with 60 % ocean blend Fox Farm.i should not have any nutrient problem like potassium deficiency at this time . My soil is on fire so to speak. Could it be on too much fire? Only soil no additives . The pot is heavy... anyhow They are at day 20 . I went out of town for 48 hours. No attention like moving , watering, spraying top layer of soil to keep moist etc. they are on 18/6 light schedule. Humidity is 46-50 % and temperatures are 72 ish. Lights were around 30 inches at the time of”burn” I cut the fan leaves that caught the brunt end to expose some of this undergrowth. I feel like this grow may end up another experiment. Here are pics. Any solutions other than one I think it is LED light burn ? The last picture is after I cut the burned leaf

Looks like nitrogen deficiency to me since it’s not all burnt on the top growth.

Thanks but I tried to head off any nitrogen deficiency solutions in my explanation. It’s not that. My soil is on fire! Full of nitrogen. Nitrogen for days . This problem attacked the third set of alternating fan leaves and that’s about it. If you look close the tops got it and the tips are brown but you gotta be here looking at it
I just took these from every angle and even pulled the leaves out the garbage . I’m certain it’s LED light burn but wanted someone else to verify . I’ve had P issues and now P, guess K is next lol

Yeah fair enough, was there growth above those leaves when they started to get burnt or were they the top of the canopy at the time? They look like the rest are solid since

What you see now was below the burnt fan leaves . I’m watching them now and they seem to be rebounding. The sit about 14 inches lower than when I left them for 48 hours. I’ll never do that again in early veg

You say the soil is hot but you refuse to believe that it could be the culprit? Nutrient deficiencies are not solely caused by lack of an element. Too much of any one element can cause lockout situations which will present as a deficiency. Fwiw.

I don't run soil so I have no idea how layering everything in there effects the plants. It's possible that's it's just a growing pain from the plant getting settled into the container/medium.

Hopefully a soil guru can help you out more.

Only been using led lighting for a short time but I have experienced the burn

I wouldn’t pass up a deficiency just yet seems too isolated to be burning imho.

I agree, if it was just the top leaves and they started to twist I’d think that they are getting burnt from light. However with other growth just getting spotty would be a deficiency, unless it was overdone and it’s locked out that could do it too. Guess just see how it progresses and make sure you’re watering (ph’d) enough but not too much of course.

Nope this is what I saw, this was my plant. When LED’s burn the leaves do this curling inward and turn away from the light which is what my plant was doing . Why the burn was isolated to those particular fan leaves? Who knows. The other leaves got scorched too, you just can’t see with pictures. There is burn all over just not bad .
