    It won't be heat stress if your max temp is 25 degrees, possibly nutrient burn on the leaf tips?

    Have you measured your run off ec?

    thats light burn,not bad but will affect the top of buds all the same and will get worse if left as is,leaf tips will start to point upwards and affected buds will become devoid of thc .

    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.

    Thanks for the replies lads.
    Yeah if you look at the first pic in the middle there is about 5 colas that have gone like white and hard, I think it's from getting to close to the bulb
    I've now lifted the light so hopefully will heal
    Thanks lads
