The top of my plant is totally dead. There’s no physical damage that led to this (like a broken stem or something).

Cut that shiit off right away ....you could have a stem borer , like a worm that hollows out yer stems ,
I have had it before ...
I dont know what it s called but it doesn't stop cause you dont know where he's at .

You could lose more

Good luck

Peace
