You might have taken additional weeks to complete the current growth cycle.

Suppose a growth cycle is scheduled for 12 weeks, but it takes you 14 weeks to finish. During weeks 13 and 14, no upcoming schedules will be unlocked. This is because they are part of the next Growth Cycle, which will be unlocked only after you finish the current cycle.

Your next Growth Cycle schedule will be available from week 1 after completing the current cycle.
