    Ive not feed any neutrients yet, only water.

    Pot size : 7.5L next grow will use 11 L (3 gallon )
    Soil type : Gold Label, Special Mix Soil 20% perlite.
    Nutes : Biobizz (Grow,Bloom and Top max)
    Airtemp (Lowest 20c, Highest 28c)
    Humitidy/Rh : 40-60%
    Lights : 2x Cheap 600w led panels true watt checked with power measurement and it showed 424w for both
    Light schedule : 18/6
    Tent: 90x90x160cm
    Ventilation: carbon filter with outake fan, a table fan, a computer usb fan that blows upwards.'

    Looks like the soil is just a little hot. ( meaning too much nutrients in it-nothing to do with temperatures ) Keep giving them nothing but water for another week or two and it should sort itself out.

    Is it just at the top of the plant? and you had spayed them just before taking the pic??

    Can you get a lights off pic up without the spray so we can get a good look at those leaves, and the location of them on the plant. Im think, if its just the top, your light might be too close with the fan blowing directly over the top of the plants, and you have a touch of fan burn. Its unlikely to be hot soil, as they are already used to it by now at their age, have you added any sort of food at all to the medium?

    I was thinking it was odd that the burn was starting now rather than when they were small.. Is there any kind of time release nutes in that soil? Could be what macky suggested also. But would it make sense that only the tips burned Macky? Wouldnt the damage be across the leaf?

    Had this issue with my first grow using miracle-gro soil, never really had a problem and didnt spread on the leaves, just the yellow tips on most of the new growth but i was wary about using nutes as i didnt want to proper burn my plant.

    Sup guys, the fan is not blowing on the top of the plant and ive not added a single drop of neutrients. Just water, and yes i sprayed the plant before i took the pic. I had the lamp about 35 cm from plant and now raise it to about 45cm.
    Hope that will do it.

    The fan is blowing on the bottom of the stem

    Depends on how the wind blows, must be slow release stuff then maybe you think? Iíll have to get the charts out to have a look and I forgot where I put my shit lol. Have a look in the infirmary and some of those charts? Maybe itís a deficiency? Some will show up like that

    Agree soil looks high EC. It will sort itself as it grows, just continue to bare water feed. You could do a mini flush to dilute it down a bit

    This also explains the relatively dark green veg colour too

    Some strains don't mind, others do

    Just make sure the burn doesn't move up the leaf anymore
