Sorry in advance, I can't get any pictures.

I've had this goliath beetle larvae for the past 4 weeks, it's already fairly grown, i think (41g), but it dropped to around 36g, it's also been moving around quite a lot, sometimes hanging out on the surface of the soil not moving, but its color is still whitish-yellow.

I'm new to keeping beetles and even more to keeping beetle larvae, is it starting to pupate ? Should I change the soil to a more adapted one for when it'll pupate?

Thank you !
