Planning of periodisation

Can anyone help me with basic preparation? My overal plan is 21 week of preparation to my first competition. I am not sure how long do Anatomical adaptation, Hypertrophy (if so), Max strength preparation, Convertor Maintain…
My sudggestion would be:

AA- 6 weeks
Hyp- 3 weeks
Max- 9 weeks
Con(maint.)- 3 weeks
than competition period.

What do you think? I’m 5-11, 172, 33 years old
