N. Tabacum x N. Rustica

Ouch. Sorry to see that.

Have you successfully grown them before in pots that size before? I ask because they seem a bit small to me.

That said, I have yet to grow tobacco so my opinion isn’t worth much.

Oh no! Since it didn't perk up with water I suspect you are right about a root problem. That looks just like a brassica that had its roots eaten away. I am curious if something ate the roots. Since its a possible hybrid it could also be an abort as hormone levels change toward flowering.

My vote is on root problem. The stem looks robust. So, there's some hope for recovery.
