Time to give up??

I had a similar issue with GSC autos from ILGM. 10 weeks into growth and it hadn't even started flowering. Could just be a bad cross

Raise the lights on time to 18/6 and see if that doesn't induce flowering.

If the color is as per the photo then I'd keep veg nutes up at this stage, it looks a fraction low in N but nothing to worry about. Maybe give them calmag nitrate suppliment and keep that up through the transition. Monitor color of leaves, look for lower ones darkening up especially at the tips first, that will be a sign to go full bloom and no added nitrates or very little

Should I fertilize using transition or flowering dose?

Mine are the old, built like a tank timers with the tabs that click up or down to set
power off or on attached lights.

Sorry man it's really frustrating to see this. Mines outside the tent also, bought a new one used it just in case.

Check your timer. Change to a wifi PowerPoint you can automate ir just simply set a schedule at the power outlet. Simple and almost fail-safe. I use em here and they are rock solid reliable

As far as I can tell, no stray lights.
Will remove backlighted LED thermometer from the tent.
Analog timer located outside the tent.

Keep em going.

Any stray light getting to them in their dark spell? Backlight PowerPoints, LED screens. Is your timer analog or digital?
