Non auto showing sex at 3rd week ?!? its normal?

Hello folks!!
I'm a little concerned about what is happening to one of my plants...
Im in 3rd week of vegg @ 20/4. I intend to use this plant for Mom for my future clones, its a bulk seed northen lights fem. photo strain.Today I noticed that it started to show signs of flowering, I wonder if this is normal at this stage @ 20/4.... Or maby is an auto strain given to me by mistake??

one pistil or preflower ? picture?

ok im getting picture now...

...just taken...

Please can anyone tell me if this normal for photo strain....

Yes it is normal some strains will show there sex quicker than others.

i never heard of a non auto showing in 3 weeks under 20/4? makes no sense.

Ok i call my friend who gave me this 2 seeds and we found that this is Northen lights Auto :/
I treat this 2 plants like they are photo and for taking clones...
I take 4 clones ...lol i wanna continue and see what will happen... 2 cuttings are 4days old other 2 are taken yesterday... they are under dome and misted with Rhizotonic... still no roots...
Now got 2 different projects... recover main 2 plants and make them fluorish till end + experiment with clones of this auto...<--
I do not rely on it but wanna see what will happen

Definitely i can see signs of flowering... an autoflower flowering... i can see bigg difference from yesterday

yup figured it was auto

I decided to try G3 acid.
Anyone have good link how to make hermie with G3?
I will try on this auto to make seeds, hope im not to late ...
I read about is good to start with 100ppm solution on 20-24 day from 12/12, but for photo type strain i didnt found when to start on auto strain.

My nirvana white widows always show first sigs in week 3. Should be normal
