raise your lights ,the affected leafage wont repair so youll need to watch unaffected leaves for further signs.
light burn and heat stress are two different things and arent always related ,light burn can also appear as nute problems that will then dissapear when youve corrected the light balance.
can also get light stress from using a 24hr lights on theme,even if lights are way up high,it just happens slower and less noticably ,and this can also become confused with nute defs etc.
ive just had two months of this,mixed in with heat problems and low rh and it can become almost impossible to seperate the problems or even correctly identify them.
good luck with grow mate.
