I have I question for more experienced growers than me, and is this a light / heat issue ? I turned up the lights to 50% and in 2 days I saw this result . Temperatures are higher also because of the heat wave , currently at 27-28 C when light are on. Air humidity is 60 - 66%.

Yes this can be from heat stress 28 is a little hot I prefer 24/25. But they can take 30c so 28 is still in the safe zone. It can also be from the fan , if a fan is directly on a leaf they will sometimes taco or claw over . Main thing is your plant looks healthy so it can take a bit of stress .
