    My grow...

    My two obsession females have some yellowing. I thought it was the usual nute problem but just a friendly yup would be great.

    Its a bubbleponics grow.
    One 130w dual spectrum cfl. I know I need another one minimum but funds and honestly fucked at the moment.
    Temps always around the 30C even in the darkness.
    Its on a 20/4 light schedule.
    I have two obsession feminised seeds named lucy and sharne and a auto who is desi. Yup im a girl and they are my stoner gfs.

    Anyway id just like a yup they are looking ok, or idiot newbie you need to do this.

    First picture is lucy two days ago

    Second is her tonight. She has been my poor battered girl that keeps going on for me.

    And the bottom is desi my auto who keeps on smiling along for me.

    Oh and they were planted xmas day as my present to myself :)

    struggle is the enemy,
    weed is the remedy.

  2. Based on pix alone, appears to be Mg deficit. It would be ideal if you would supply more information. Observe the questions in red.
    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.

    If there is leaf discoloration please TAKE PICTURES WITH ALL GROW LIGHTS OFF, ESPECIALLY HPS & LED's. Taking pictures and taking them with lights off, allows us to see what the leaf discoloration looks like.
  3. I would say Low N.  N is the most used nutrient by marijuana, and is the cause of like 3/4 the yellow leaf posts I've seen.  I agree that the pics look like low magnesium would look, however if you arent feeding and NPK now then you should try some N first.  Mag is a very unpopular defficiency and usually only happens with slummy city water.
