I have a few torches that are doing good at all and can't figure out what's going on. All my parameters seem to be alright, not perfect but dont think it would cause this, could be wrong. I thought it might have been a light a flow issue so I moved them to more suitable location and it seem to help most of the heads except this one. This morning I noticed most of the white flesh on the septa( sorry if that's the wrong terminology) is almost gone in the past 48 hours or so.
