LED light burn?

  1. Hey guys what's happening! I have a female plant that's flowering under a 100w diamond series led light. I have a full ventilation system but I've been getting light burn? The lights about a foot an a half from the top of the plant..any help would be great!

  2. Shouldn't be burning at a foot and a half... :confused:

    I've seen grows with the DS100 that were at 6-8 inches without burn.


    But I don't know what's that burn though...
     
  3. Looks like phosphorous deficiency. What are you feeding it and are you pH'ing your nute solution?
     
  4. I've been feeding her tiger bloom reg dosage (she's an autoflower/in flower)
     
  5. do you check your pH?
     

  6. agreed. your plants would look more bleached not scorched from the LED.

    Looks like you may be having a ph lockout or phos deficiency. You may have to flush your medium
     
  7. What strain is it exactly? I know some most autoflower strains are finicky with nutes, especially if they have blueberry in they genetics. Could be a nute burn or something - just my two cents not entirely positive. Subbed - do you have a journal ?
