Depends on the genetics of the strain. Sativas typically will take a couple weeks longer to flower than indicas. (under same conditions)

So if you know the expected flowering time of you strain, you can estimate how long it will spend stretch, and how long for fattening.

For example (10 week estimated flowering time period):
10 weeks * 40% = 4 weeks of stretch, 6 weeks of bud-fattening
