I would say its a combination of wind burn and low humidity for the temperature.
VPD charts show 27 @ 55h rh would be around 1.5 kPa which is very close to the danger zone. either lower the temps to around 23 or increase humility to 65.
If all of the plant is showing the claw then I would agree with AlicePhaedrus. But it looks like its only the highest growth which gets the most heat/wind.

- has VPD chart.
This looks like it may be the first stage of nitrogen overload.

You may be overwatering the plant a bit too. Let the topsoil go dry about as deep as the first knuckle on your finger - half an inch or so.
Humedad 55% y temperatura 27⁰
Pero no creo sea eso porque de tres plantas de misma genetica solo en esa me ha pasao... estan en la tercera semana de floracion y de abono le he dato muy poco hasta ahora..
Could be a number of things, my first guess would be wind burn. Could also be nitrogen toxicity. Low humidity and high heat. What's your temperature, humidity, feeding amount
