Flowering week by week?

Good afternoon everyone. I hope i find you well.
Just a quick question to see if i can get some opinions. Do you think/know if there is a specific timescale i.e week 2-3 or say 5-6 for example where buds grow larger more quickly. Or is it a more gradual progressive thing from 1-10 ?
Hope this makes sense. Just learning so pardon the boring point.
