yellowish looking leaves

Discussion in 'Sick Plants and Problems' started by GFresh, Jul 1, 2009.

  1. I did a search and found some useful information but still not quite sure what is wrong :(:confused:.

    The grow is in soil 1/3 organic mix, 1/3 perlite, 1/3 compost.
    The plant is about 5 weeks old on 18/6 with a 400w hps.
    Grow cupboard measures 1700mm x 700 x 600
    Ph is at 6.2 and watered with rain water.
    Rh sits between 40% and 60%
    Temp sits between 26 and 32C
    Not sure the EC
    1 dose of 1/4 strength Ionic nutrients has been given 1 week ago.

    Not sure what other info you may need so here's some pics.
