Possible Fugal attack, what to do now?
Background:
I'm growing in soil ( foxfarm ocean forest ), multiple strains, cfls for veg and 400 w hps for flower.
I've been battling this borg for a long time, and am at my wits end on what to do. So any advice would be appreciated.
I've tried all the nutriant and enviromental based solutions, such as adjusting ph, NPK ratios, etc with no positive results. I've repeatedly flushed and treated the root zone with h2o2 to kill any root born pathogens.
This shows up on seedlings, clones and mature plants.
My water is from our well, and no I havent had it tested. The ph is 7.0 and it does have a fairly heavy mineral content. I do not have a RO filter for the water installed. I have had succesful grows without one up to this point.
I generally feed my plants with Jacks Clasic Citrus Feed 20-10-20, although I have used other products, mostly earth juice. It doesn't seem to matter what or how much I feed, I still have this problem regardless of what I feed my plants with. This shows up in seedlings that have not been given any nutes at all, as well as mature plants that are being given a regular feeding.
I use supliments for trace elements and for calcium and magnesium. Again, it doesnt seem to have any affect on this problem. I've tried different supliments without noticable improvements.
Temps have varied from 60 deg at a low to 90 deg at the high end. My flower room has temp controls to keep it between 65 deg and 75 deg. My grow room temps are also stable at the same temps. Humidity is beyond my control, but generally is around 40%, depending on the weather. This seems to happen regardless of time of year and humidity.
I've come to the conclusion that what I have is some kind of fungus that has spread to virtually all of my plants. I've been trying to treat it with seranade, without much in the way of success. I am now trying a copper based fungacide, again with limited success.
The symptoms seem to start at the edge of the fan leaves, with a brown stain like appearance, and eventually it will kill the entire leaf. On more mature plants it will kill off all of the fan leaves, I do try to pull the affected leaves, but it just shows up on the other leaves. Harvest is severely affected, trichome count is affected to the point that the resulting smoke is almost worthless on some strains, and so so on other strains. This is probebly a side effect of damage to the fan leaves not being able to feed the colas properly.

Anybody who has had any experience with this kind of thing, PLEASE HELP!
