When does flowering begin?

Trinidad

Hi guys, im growing an auto flower in hydroponic. After day 21 she started showing preflower. Is this the beginning of flower stage for an auto flower or is she just showing me her sex? I know that photo periods show pre flower in veg. Should I begin transitioning to flower nute?

A plant can show pre flowers as early as 3 weeks of veg so no it's not an indication of the flowering phase, this is the same for Autos or Photos. Once you see pistils developing, you've entered the flower/transition phase. During this phase the plant will stretch, you will want to continue with your veg feeding and keep light intensity low. After the stretch, start raising light intensity, start lowering veg nutes, and start raising bloom nutes.

It is entering flower and it is also showing you its sex. Now that this is happening their is no stopping it. get ready for bloom. Can start to transsistion over to bloom nutrients after the strech is done.
