flowering-wise you should be fine... as long as they get at least 10 hrs darkness they won't return to veg state... but as for hermies there's no way to be sure, lighting issues
can cause that...
as the guy above me said... "just be careful"
just watch the internodes closely, and even if one or two branches hermie on you, that late into flowering it's likely they'll do very little damage since they first have to mature enough to release pollen and also it takes some time for the actual seeds to form
good luck
