It's the end of week2 and I have no real sign...

Give it time, I see you introduced bloom fertilizer it should also help to kick start but if your light cycle is correct as mentioned it's sometime normal for it to take a week or two. Just be happy your plant is looking solid! 👌💪

CONGRATULATIONS ! It's a girl !

Hi there mate Athos and longjohn could well be right however there are two other possible reasons for your plants not shifting into flower yet. They are #1 is your timer set correctly? are you certain they are getting atleast 12 hours of uninterupted darkness? #2 is a possible light leak within your tent. Something as simple as a red light on a powerboard (trust me Ive had it happen) could be enough to confuse your plants and keep them in veg mode Zip yourself after lights out and see if its completely dark Hope Ive helped somewhat 😃 best of luck

I've had that happen on strains that show a more sativa like phenotype, they can take up to 4 weeks to show preflowers; I would not worry. Do try to keep the stretch controlled.

Hi there! I think you have gave her too Nitrogen after switching to 12/12 that may cause flowering to take time to start. Get off you grow nutes maybe change water with less grow ( nitrogen ) in your reservoir. You are growing in hydro setup aren't you? Also recovering from training could postpone flowering period a bit. Hope this helps and happy growing! Looking good!
