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

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

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