Random bruising on cannabis leaves

  1. Random bruising on cannabis leaves appeared randomly out of the blue in such a short space of time top and lower leaves have been bruised, I can see these bruises will eventually dry up and then become dead parts on the Leaves, why is this any ideas, Plus on a couple of my other parts I have a couple wrinkly leaves so soft and brittle that I've had to cut them off

  4. It might not look like it but the leaf finger in the middle on the right, whole leaf is completely bruised it's so soft can tell it will dry up and die in a couple of days. And I Got 5 other plants with the same type of bruising randomly appearing on some of the leaves and a new growth is growing out with the same type of bruised leaves as well 1564345756826.jpg 1564345833083.jpg

  8. Ok...well 30C is a bit warm....it looks like, best I can tell from blurple pics, heat or light stress....

    What are your lights and how far away from canopy is it?
     
  9. x2 600 small LEDs About 19 inches away I thought these were meant to be crap LEDs but I think he might be right and I might have them to close 1564348413497.jpg

  12. Dont have it blowing directly at them or yes they can get wind burnt,,have it blowing slightly above canopy as it mimmick the wind in nature and helps strengthens stalks and branchs

  13. Exactly that man you only really want to see the plants get a faint breeze at most, that will minimise any heat buildup across the canopy.
