Is the flowering developpment normal?

I'm new to growing so each step of the development for me is new. I started the 12-12 flowering stage 2 weeks ago and i am not sure that the development is normal because I see no bud only leaves, is it normal. The strain is blueberry. I add a photo to help!

Thanks.

Some plants take longer than others, it's maturity also affects how long to flower. How long did you veg her? Seed or clone?

...but 2 weeks, I'd be a bit concerned. Check for light leaks. My rule of thumb - no direct light whatsoever, and as dark as a moonless night.

Good luck

The vegging was 4 1/2 week, after that period the pre sexing was apparent on 80% of the plants. Growing from seeds. Effectively after the first week of flowering I made some change to the tent to cut some source of indirect light. It's quite better now. I can see pistils on the plants but it's really at the beginning. Thanks.

Should be fine, keep light leaks to a min. Two weeks and pistils (white hairs) starting to show is normal, sometimes it shows quicker. Yep it is a long road or at least it seems that way sometimes! They will slowly grow and turn into buds keep watch to ensure no males snuck in there too.

Also your plants are showing some leaf curling and a little burn possibly. How often are you feeding and what are you using?

For the veg i was feeding with miracle grow all purpose fertilizer (24-8-16), i started with a dosage of 25%, 50% 75% and 100% one time a week. For the flowering I switched to GH FloraNova (4-8-7) with a dosage of 50% then 100% also one times a week. My plants are nicer since i use FloraNova fertilizer.
