Yeah I don't shut off my light until my canopy is 105 and other than a little bit less dense I don't see anything like that. So it isn't heat.Is it from a clone you brought in recently? It almost looks like a pest issue to me. The heat isn't doing that at 78° as that's on the cool side for LED growing. It could be light stress but we need to know the ppfd level at the canopy, what you've been feeding, and some whole plant pics would help as well.

105 degrees fahrenheit. I grow without air conditioning in my house in the Mojave Desert. I've seen heat stress a lot.I don't understand this.
"105" what?
Your AC controller app is displaying that a device is at level 4. What is that?
Severe canoeing/tacoing like that is a symptom of light stress.
Your VPD is spot on so I'd think that it could be too much wind, too much light. Add I the nute burn on the leaf tips and increased window and or light could be driving up transpiration which is causing the nute burn.
Has water consumption changed markedly in the past few days/weeks?
^^ this you really need very good air flow tooDo you have air flow / exchange in your grow area. ?
I turned the fan up to four to try to combat what I thought was heat stress. Tried to get more air flow in the tent.105 degrees fahrenheit. I grow without air conditioning in my house in the Mojave Desert. I've seen heat stress a lot.

Also if you have high heat you need low humidity I'm under 20% in the summer. That's how I can survive such high heat. I hope that clarified it a bit. Sorry for being confusing. I'm good at that.
No, it's grown from a seed.Is it from a clone you brought in recently? It almost looks like a pest issue to me. The heat isn't doing that at 78° as that's on the cool side for LED growing.
