Seed sprouting delayed?

  • I have noticed this last few days that my seeds are taking longer than 4 days to sprout. I always keep them watered and with full sun.
    Right now a seed I took almost at the same time as another still hasn't sprouted while the other one is already a sprout.

    What would be the reason for this? I am worried that the seed is stuck like that and I won't be able to pick a new one before the Halloween event is over.

    I have also noticed that some of my sprouts also take longer than 8 days to become fully grown.

    I know that if they dry up the growth stops until it's watered, but this isn't the case, I have kept my seeds with water and sun and they still take longer.

    I appreciate any help or insight into this ^^
