Hey, put a diary please with documented feeding, best is to tell ph and ec everytime.
Also we then can see the exact seeds your using. I cant tell from your post if its a photoperoid or autoflower.
Autoflower you should start to see white pistills now, you can see them as the ground structure, like when u build a skyscrapper and there only the metal part up. Buds will form around them.
If you have a photoperoid it depends on when the day gets shorter, its needs a daily nightcycle of 12, minimum 10 hours. You have to wait for late summer so the sun hours get less, depends on your season. You can when she close also shock her with 48 hours complete darkness and then put her back, that will fasten the process for photoperoids.
