Auto flower with no side branching

Hello, looking to see if anyone else has had this problem. I’m growing northern lights auto from Seedsman. Optic 4 LED, temp between 72-76, humidity 50-55%, coco, air pot, GH trio neuts, feed/water PH 5.8-6.2. The plant is 6 weeks from seed, looks healthy for the most part, but has NO side branching.
thank you.

Another pic.

It could be the the ruderalis genetics used to make the auto. They don't branch much. That looks like the ruderalis is extremely dominant in that plant. Also looks like you need to cut back on the nute strength.

Here's a Ruderalis I grew. It had minimal branching.

Thanx for the reply. Did yours flower?
