No worries, my australis male got the same problem and he is OLD and eating as supposed to for a male. If it is not bleeding, it is ok.
About 2 weeks to i2.. then it is a very long wait. I believe from i2 to i3 is one of the longest waits... Androctonus take as much as three months.. I am making a sheet about my androctonus average moulting days.
My bicolors from i2 to i3 average out at 87 days.
