This is my Grammostola pulchra that was 1.75" DLS prior to this molt. I'm not even sure if it is possible to determine their sex at this young an age, or not. If it is, based on what I see, I'm leaning towards it being a male, but I don't have much experience with this.
Hopefully you can zoom as needed. Definitely observe absence of female reproductive organs at this point. Curious if female vs. male distinction is apparent regardless of size (just some molts are too visually small to sex) or if there is a particular stage in life when female/male organs develop?
