    Help with grow, leaves look ill - Pictures available

    Hey, thanks for the replies. If I can only spray my leaves with budblast when lights are on then that would surely burn the leaves, with 1200w in there it can get a little hot lets say, hence why I always spray the leaves when lights off. Jamezsr - Can you suggest something to bring the PH down...

    What sort of PH should I be looking at? I do have an extractor fan and a small fan circulating air...Maybe I need to upgrade the fan to a larger one. I will leave with no water for close to a week and let them dry out and start again. Is 1200w too much for them you thinking?

    CFL or Sodium???

    Also I have learnt that if you take the lighting to the extreme and pump in 2000 - 3000w etc then you cna pretty much kill your plant as it's getting bombarded with so much light it just goes weird and eventually dies! This I do know as my mate tried it rather nievly, and what a disaster!!!
