So I have these little spots of less density in some of 4x5 negs lately. They aren't completely clear clear like dust would be and have been happening in clear skies. Did I get an iffy batch box of Tri-X or is there some chemical process that could cause this. Could too strong a stop bath be the culprit or leaving it in a permawash too long cause something like this. I'd like to avoid it if possible. I thought maybe it was drying marks also, but am using distilled water and LFN. Anyhow, as always thanks in advance and you guys are the best!
