Switching To Flower: Help?

Hey guys,

Usually I grow hydroponically indoor auto flowers but this summer I decided to try outdoor, soil, photoperiod plants (its working out great! I have some pretty good sized ones).

I planted these may 23rd so its coming up on 2 months of Veg, I was just wondering how I put the plant into the Veg phase since they don't "auto flower". I have been using fox farm nutrients and just hit it with sledgehammer and a nice flush. does the spectrum of the sun just change at a certain point in the summer or is it just the fertilizer switch that makes the plant flower? just wondering how I can initiate flowering!

Thanks guys! I also am growing a auto flower outside shes about 2 feet tall and ready for harvest in about 3 weeks, its the only plant in the photos with buds on it!

Photoperiod will switch when the time is right. They should start budding pretty shortly from now.

In other words, you don't tell them when to flower, Mother Nature and the change of seasons does.
