  2. We need all the info on your grow including:

    What type of medium; soil or hydro?
    What brand and type of soil?
    Indoors or outdoors?
    What strain?
    How old are the plants?
    What type of lights and how many watts?
    How far from the lights?
    What is your watering frequency and source of water?
    What, how much and when was it fed? NPK?
    What is the medium/runoff pH and PPM if in hydro?
    What are the temps and humidity in the room?
    What size pots?
    Any bugs? Look real close.
    Any other pertinent info?

    If any of these questions have already been answered please disregard as I cut and paste this for everyone.

  5. check ur ph. if its not within proper range, it can't uptake the nutrients ur feeding it. looks like nitrogen deficiency.
     
  6. What kind of nutes are you feeding exactly? 
     
  7. Ph is at around 8 it's only the bigger leaves at the bottom all the others look fine
     
  8. It's supergrow liquid plant nutrients came with my hydroponics system
