Weird plant showing no sex characteristics

I have a very mature (3’) unknown indica strain that is showing no sex attributes at all. No pistils and no balls but is starting to get covered in tricomes. (super healthy too)
My other 4 plants are 2-3 weeks into flowering and covered in buds.
I forgot to mentioned that they are growing outdoors in pots and they all received the same treatment.
Any ideas on how to induce flowering or did I just get a weird dud.
cheers.

i would think if you have trichomes you should have flowers… Most trichomes will begin appearing at least 3 – 4 weeks in the flowering stage of your cannabis plant… upload a pic when you get time.

Have some pictures?

I spoke too soon.
Just noticed pistils starting to show this morning.
Hopefully all ends up going as per normal.
