Do y'all count days flowering from the date of flip or date of first pistils?

I count from the flip and slap a label with that date on the pot. It’s really to remind me where we’re at in the cycle, when to start checking trichs, and helps scheduling the next batch for “promotion” to 12/12.

I count from day 1 of flip to make it easier to read nutrient feeding schedules, its especially important when adding stuff like terpinator or hum bolts secret or whatever, or big bud

I’d like to predict when my flower box is going to be empty to receive new plants.
