Got some 'giant' hisser nymphs the other day. this is my biggest. Noticed tell-tale white lines mainly on the gaps between segmants near the head. how long should it take to molt? How can I observe it? Do roaches hold off molting if stressed?
I have some Black Tiger Hissers that had "stretch marks" for a long time before they molted (MONTHS). They are all doing well and molting activity has increased with the heat of June. Seems to me you don't have to worry!
