the development pace is typically similar.. potential variety just the same.
so figure it started 2-3 weeks before you saw tufts of pistils at terminal buds. if the preflowers didn't pop early, figure 5-7 days before you saw those... the older the plant is the less likely you can use preflowers to guesstimate.. they will pop evenetually, regardless... then you can apply that typical 8-10 week time frame from then.
30-40 days from that point should see plumping.. slower strains may be in the 40s.. faster strains by early 30s.
once the plant shifts gears, it's the same timeframe as photos, but we just don't know when it flipped for certain just by looking at it... you don't see the results until several days later. forming new organs takes time before you can see it ocurring.
