Why no flowers?

I have a strain (Vanilla Tart) that I have been growing for a while. Usually I see the first flowers in the first week. The new girls have been in the flower room for two weeks now and still no sign of flowers. Does anyone know why this might be happening?

Have you checked all your timers and relays running your lights.

Depending upon maturity it can take 7-21 days for flowers to appear. There’s a lot of factors that can alter that time frame.

Temps, light levels, nutrient levels, humidity, air movement, training methods, stress levels just to name a few.

Thanks for the quick reply.

7_21 huh?
Yeah, that is why I mentioned that she had flowers in a week on previous grows.

Lights are on and off on time.
Temps are higher than previous grows, not much I can do there. Strike 1
Light levels are probably lower, fourth grow on that bulb. Strike 2
I changed nutes for this grow, maybe something here.
Humidity is reasonabley stable.
Air movement has been stable.
Yep, training her different, experimenting with scrog this time. Strike 3

I guess I will just have to add a couple of weeks to my projected harvest date.
