Dark stains on leaves, looking for the cause

Well the least you can do when you have such an enormous stuff to post is politely give a link instead of clogging the whole thread with it. And as I already said, I am looking for someone else's OPINION, not a guide that I am already reading.
That's fun anyway that this kind of rude and gross behavior only happens in this community and not the other ones where I posted the same post and it was kindly answered and led to a POLITE discussion.

As said earlier I'm not interested in arguing with that kind of people, now that I made my point clear I'm not following on that anymore.

i am a few months late here but what a loser this guy is no one can add to his thread only give him the exact answer loser that is what i say and GOD BLESS ALL OF YOU EVAN THE LOSER THAT STARTED THIS THREAD
