When did flowering actually start?

At 34 days old one of my plants was found to be a girl while still in veg stage. I turned to 12/12 around 54 days old though. Did the plant atuo flower at 34 days or a couple days before that? Cause i heard of many people saying that after the plant is put into flowering they see sex a week or 2 later.

If my plant did start at 34 days it would be 49 days into flowering. Is this about right or has she been flowering longer?

Appricate any help

unless it is autoflowering, it won't start untill 12/12.

Well, there are a few things that can cause early flowering and they are all forms of stress... Too much heat, not enough light, not enough water, not enough food, constant handling, fan blowing directly on the plant for long periods of time... ect. any stress can cause a plant flower early but keep an eye on the early girl... she might hermie and become asexual as a method of survival.
