Flowering?

Flower phase started before you can see it... on the cellular level. You are probably ~2 weeks into flower, give or take, based on development of terminal bud. If it is an autoflower, then you can only estimate when it went into flower... mayb 5-7 days before you noticed 'preflowers,' which are the single calyxes that form at base of a branch. if you noticed them when they were tiny nubs, maybe 3 days prior? the only autoflower that'd be a bad way to estimate is one of those long-vege XXL autoflowers... they might vege long enough to produce preflowers in vege phase. if photo.. you know it's in flower when you flipped to 12/12. That's as close to apples to apples way of measuring as you can get with an auto... unless you work in a lab. Except for how they trigger flower phase, the time to develop flowers and such is not different in autoflowers. They are not faster. This is a misinterpretation or lame marketing strategy preying on ignorance.
