Likely too hot and stuffy in the box. Plants still need to exchange gases during their night cycle. Try a much larger box, that holds more air.

It starts flowering at the highest 3-5 nodes first- that is where the plant's hormones are most active. It should take about 7-10 days to show sex. You got a couple to go.
