great, thanks. I think I'm going to call the white habs a total loss and get rid of all them and all the containers they were in, but I'll spray down the remaining plants tonight and keep a close eye on them.
Coincidentally, I also live in Madison, and I'm also growing peppers, and they also are having some browning (just like yours) and yellowing. I do have some problems with whiteflies (I think), but the damage they make is just little light brown splotches. I'm not sure =/
Despite the crappy weather, have you managed to put your peppers outside at all? Maybe it's some kind of scorch damage.
JZydowicz, what kind of peppers are you growing?
