Day25, One of my strains entered pre-flower, I increased PPFD, leaves are praying again, good sign. Is this when they will start stretching? Never grew autos B4.

The strech period should be the same for auots and photos. Starting within a few days of “preflower” how much and for how long will probably be dependent on environment, strain and genetics

Yes, your auto is about to stretch and go into flower. When I notice pistils on autos, it’s usually less than 2wks that they are in full on flower.
Photos will only flower on ~12/12 even after the appearance of pistils. Pistils first appear only indicating sex and that the plant is mature enough to flower. With autos, pistils are a strong sign that you are soon going into flower and the light schedule doesn’t matter.
But right now is when you want to avoid any heavy trimming or training. She is starting to transition and doing so could stunt her growth and really hurt your yield.

Tread lightly with the lighting intensity…leaves standing that straight up are indicative of too intense Growmie
