What’s causing the leafs to do this, heat stress?

[Al8]

Never over 23 degrees in tent, all of them look like this

How close is the light? Even if the temperature of the tent is right if the lights are too close the plant can be taking some serious heat, I usually place my hand and if I feel heat I pull them higher. Did you start feeding them? If so when? What nutes? What soil? Could also be nitrogen toxicity or something else, more people will chime in to help but they will need those questions and probably more answered.

How often do you water?

 

[Al8]

light probably 800mm away from top of plant, on 40% light intensity with a 450w led.

Have just been feeding them water for the last 3 weeks once every 3 or 4 days been in a vegetable soil mix since rooted clones.

That doesn't look like heat stress. It could be a disease called "beet curly top virus."

The virus is interesting. It almost looks genetic. A little scary too....

More like something interfering with the genetics. AI8 says it's happening to all of their plants....

Were all had one of these, right? it's rare and usually it's one mutant, and we get rid of ir.

Here’s a video if it helps, definitely strange

Actually Ive never heard of it. I went to wikipedia to learn a bit more and it says its more of a western USA thing. Im glad I dont have it here
"Beet curly top virus (BCTV) is a pathogenic plant virus of the family Geminiviridae, containing a single-stranded DNA.[3] The family Geminiviridae consists of nine genera (Becurtovirus, Begomovirus, Capulavirus, Curtovirus, Eragrovirus, Grablovirus, Mastrevirus, Topocuvirus, Turncurtovirus)[4] based on their host range, virus genome structure, and type of insect vector.[5] BCTV is a Curtovirus affecting hundreds of plants. The only known vector is the beet leafhopper, which is native to the Western United States."

EDIT: Its also known and present in Spain but Ive never had this happen to me so I guess is not as common. Maybe in the south of Spain where there's kind of a desert, they like those areas apparently.

I’ve never heard of it before either. I don’t think we have it here where I’m from

That's the thing, not all mutant plants have the Beet virus, it could be for another reason.

But, this thing is a potental problem, and this is only 1 virus. We don't want these......
