Is my VFT already gone dormant?

[powersensor]

I have a small VFT divided from my large mother plant. It is around 50 cent in diameter and was doing well until recently. The whole plant started to turn dark brown (going to turn black). All leaves and traps are still intact (still rigid not soggy). Is this a sign of the plant going dormant?

I have removed the water tray and try to keep the media barely moist and give it shadier environment. Is this the correct treatment for VFT going dormant?

Will post photo later. Thanks.
