Avicularia versicolor sling pre-molt time

[Ratmosphere]

How long do slings of this species stay in pre-molt? Does it differ from each individual? I have one that has been in pre-molt for about 3 weeks but isn't looking skinny.

heavily depends on temperature and the individual. not to mention size.

Does it differ from each individual?

Yes, differs w/in the same specimen too. They aren't clones, all different.

I keep them at 70 degrees Fahrenheit and feed the half inch slings every day I can. However, one sling lost a lot of color and its abdomen was turning purple. I checked today and all of its patterns are back with no signs of a molt. It still does not want to eat though. Just confused on what happened.

Should I be worried?
