Do anda need to get back to your brewing Potion at exactly the right time atau could anda also finish it e.g. the seterusnya day?

anda have an jam and 20 minit to do part 2 after the gap of 80 atau 100 atau whatever minit between the two halves. If anda don't start the saat part of the potion within that jam and 20 mins, the potion screws up. So no, anda can't leave it for the seterusnya day.

I can't even find the potion I have brewing at the moment, is that normal if the time's not up?
