did ya sort it out bro? i have had same thing happen to me in 2 different locations, first time it fucked me big time and after tryin everything i finallly moved, started creepin in again after a grow and a half in new joint and i was ready to head for a tall building.

old timer i met online suggested i add food grade ozone to my water 3 x 5mins a day or equilivant as long as no more than 15/day. was skeptical at first but my girls are back to full health now and boomin.

as to the source of the problem after eliminating almost everything, i tried every different combonation and remedy and then some i can only put it down to a bacteria build up. i use silver tape on my buckets as well as duct tape round the hole in the lid for the netpot. i noticed under both lots of tape there was black bacteria buildin up that h202 and other shit just didn;t seem to knock down, ozone whilst not removing it seems to kill any nasties associated with it.

not sure if it'll help in your situation but your symptoms and description are exactly the same xcept mines dwc and i'm not sure where the bacteria is coming from in your gig.

peace
