m0useanswered grow question 3 years ago Autos start to go into flower around week 4/5. this is a natural cycle for them and they do not require a light switch to bloom, they just do it.
your main factor for a good yield is going to be your light intensity.
or future questions link your diary to the question so people can get a better understanding of your grow.
I do not see your light specs but try and give them as much as possible in a 18/6 or 20/4 cycle with lots of food, follow its instructions on how to feed.
Good Luck
