Never ran into this….need some help

Hello, I’m having a an issue w/ my current grow. I was given 2 plants by a friend about 3 weeks ago. They were in sad shape to say the least. They were 5-6 weeks old, hadn’t been topped or trained so they were very vertical. I nursed them back to health and they look great now compared to before.
They’re almost to the point of flipping to flower, but I’m seeing an odd condition on a small number of the leaves.
After transplanting to a 5 gal pot and letting them adjust, I cut the top 1/3rd of the plant off at the main stem. This left me w/ 10-12 main tops that I tied down, with a bunch of exposed sites in the dead center. Now all those exposed sites have started new growth in the center, with the main tops forming a circle around the perimeter. The canopy of nice and even.
The issue is many of the new small sites are looking ragged…..tips burned or very dry around the edges.
The main tops are 99% great…..but there is the random leaf that is dry and dying…..no discoloration at all…..just drying up.
I’m wondering, could this be a fungus that is attacking the newest and most vulnerable growth? Could the issue with the new growth be caused by the light being too intense ?
—my lights are 2 HLG led’s, 470w total….turned way back = 300-350ppfd.
—medium is FF KokoBop lightly amended w/ various dry organics. I have had many successful grows with this mix.
—temps 79-81F, RH 58-64%
I usually top a plant a couple times in veg, then tie it down rather aggressively to open it up for a flatter canopy with many tops…..but I’ve never done it this way where the sites are starting from nothing and exposed to such direct light…..
And what could cause a random fan leaf, that’s growing among many totally healthy ones, to just dry up and die?
Anyway, any help or perspective is appreciated. So thanks…

You did a nice job bringing it back, and it looks really pretty darn good. At first blush I'd say it was a little heat/light stress, but your temps and lighting seem right on. Possibly it got a bit over nuted, the leaves are a really dark green and a bit waxy. I don't think it's anything to worry about unless it progresses, my feeling is it will grow out of it. Maybe cut back a hair on N.

Yeah I’m in wait and see mode…..

Things seem to have gotten better. I’ve decided to let the 2 bigger plants go another week or 2, then flip. By then the 3 seedlings should be big enough to take outside. Pic was yesterday. I’m thinking with the stretch those 2 plants will fill up my space…..

You did fantastic nursing those things back to life. I can't wait to see them flowered.

Maybe just something leftover from the trauma working its way out. Looks like the path your on now is a good one.

Hey guys….i just thought of something and wanted to get some input.
When I set the small 3 plants outside they’ll be in my backyard. My intent will be to bring them back inside in 11–12 weeks once the others are harvested. So they’ll be vegging the entire time. However, I have these motion lights that come on frequently. While they won’t be shining directly on the plants, they could “interrupt” their dark cycle.
Will this cause any issues, since the plant is just vegging?
I grew outdoors years ago but the grow site was on top of a mountain, miles away from the nearest light..so I didn’t have such things to worry about.
Is this gonna be a problem? Thanks to all.

You'll be fine with the yard light, what might not be fine though is the amount of light that you're getting outdoors. Depending where you are at, here in Minnesota we don't get 14/10 until around April 25th....

I just thought about that…..I’m in SW Virginia and may need to hold out a few weeks.
Thanks for the advice.

taking plants outside then bringing them back into your grow room, isn't such a good idea, your opening yourself up to bugs in the grow room, just FYI
