The leaves have gotten worse even after lowering them and putting the fan on them. The new growth seems to be curling more than the old.
I stuck a 2X4 up to be at the same height as the plants and put a thermometer under it. It was at around 104 degrees.
I am not sure what Rh is and I am not sure what you mean by "ensure its about 55-65% the fan is compulsory ". I definitely need bigger pots which I will do soon.
I switched off the fan to see if it was wind burn though I don't believe it is. The fan is about 8 feet away but is blowing hard enough to visibly make the leaves shake.
I have always grown them the way I was before I started to have problems. I usually have them about 5 inches from the light consistently, around 70-80 degrees in the room and a fan blowing on them. This kind out of no where. Thank you all so much for your help!
