    Usually when I see spots on the leaves like that they are more of a rust colored and I consider them to be calcium issues, you're in hard water so that probably shouldn't happen. Those spots also look a little bit more black than what I would expect.

    Are you seeing these only on your lower leaves? If so just a general increase of feed might be all that's needed.

    With mother plants it's perfectly all right to cut them way back and let them build themselves up again. Then cut them back again and so on and so on....

    Ok thanks man, those 3 pictures are the worst, there's a few spots on other leaves scattered all around though. Ill try giving it 4ml per ltr tomorrow, cut the dead away and anything too infected and keep track of it. It'll be going into flower in a cple weeks

    If it keeps on occurring you could try a light spray of neem oil just in case it's some type of fungus.
