Leaf Spot Fungas, what to do?

Man, i am interested to see what actually fixes this for you but i have to agree, this doesnt look like leaf spot or a fungus to me. Looks like calcium def. plain and simple IMO.

I may have missed it, but are you using RO water by any chance?

Nope , just straight well water. The thing that has been driving me nuts is that I was treating for mag/cal, and all the other usual suspects. That was the problem. I went nuts trying to figure out a nutitianal, or enviromental cause and nothing I did had any real effect on bringing my plants back to their 'happy place', they just kept getting sicker. Flushing, different nutes, everything I did had absolutely no resolution to this issue. When I started treating it as a fungal infection I started to see some positive results. I may not be out of the woods yet, but at least I now think I have a path to follow.

Update: It definately was a fungal attack, have no idea what kind but it responded to the copper based anti fungas stuff that I used. I saturated my plants multiple times, aprox a week apart, and that seemed to do the trick. I still see signs on several leaves, but I figure if I keep treating them I can at least keep it under control. The sulfer burn may have helped keeping it from becomming airborn, but from the looks of it it was some kind of systemic fungas. Meaning it resided within the plant, not just on the surface as some fungi do. I'm trying to do another run of THC Bomb, as well as Master Kush and White Rhino. The last run of THC Bomb was completely destroyed by the mystery fungas and had to be pulled, but I salvaged several clones and treated the heck out of them with anti-fungal sprays and they look like they will be just fine. All are about a foot tall and will be flipped in a couple of weeks. Keeping my fingers crossed that they turn out ok, no sign of hermi's thank goodness, as I was worried that all the doctoring would stress them to no end, but that doesn't seem to be the case.

Thanks for all the help that the people at RIU have offered. I know that most people have never had to deal with anything like this, and frankly I was close to just calling it quits, but I guess I am just obstinate and through trial and error I think I have got a handle on it now. It would be nice if there was a place in the forums for these oddball kind of plant ailments (with pictures and solutions), as I too thought that it was a nutriant problem at first, or an enviromental issue. Maybe some other poor soal will benifit from what I have been through.
