Sensi NL auto grow

Hello, this is my first auto grow. She's 7 weeks old and Stillllll not damn flowering..lights are on 24/0 as per the instructions say they flower no matter what..signs of pre flower is clearly showing ( and they've been showing since 3 weeks ago)

Tried switching it to a 12/12 but got feedback that it wasn't recommended and it won't do any changes so I went back to the old 24/0 schedule.

Only feeding it with novabloom and nothing else every other day.

She went through a couple of light burns earlier but that's about it really.

Here's some pics I managed to put up. She's nice a very bushy BUT NOT FLOWERING ARGGHHH!

How are the temps in there ? If you see pre flowers then she will start flowering soon, dont worry too much about it, imo its actually a good thing shes taking so long, i bet it will be a big yielder

Temps are actually ok it's usually between 72-85 F...just had to do a lot of light adjustments cuz she started to stretch real quick
