  1. I have a problem with my first grow. The leaves are looking a bit sad (see pictures). I was told it could be a magnesium problem so I added some Epsom Salts yesterday but today it is looking a little worse.

    Temp - 20c daytime, down to 17c night time
    Soil - Compo Universal
    PH - 6.5-7.5
    Watered with Spring Water (ph 4)
    Age - 4-5 weeks old
    Nutes - One 1/4 strength Compo Universal a week or so ago.
    Potted in cut off old 5 litre spring water bottles
    Humidity 70% and dehumidifyer running
    Lights are CFL's
    12 plants with 14 CFL's

    Leaves are looking a little dry. The new leaves are a bright green, older leaves are mottled yellow with some brown dots and some are curling and dry.

    Please help. If I loose the plants or get nothing from them, my wife will kill me over the money spent so far!!
