From before you switch to 12 12, you dont want to do anything to stress her going into flower. Cheers

Light height full power vs dimmed
Hi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)

Flowering lights never turned off
Power outage messed with my system and lights didn't shut off. Need a little advice. Should I just stick to the original schedule and she will just get 30 hours of light for one day or should I turn them off.

Increase light hours autoflower
My autoflowers are 6 weeks old and showing flowering signs. Can I increase the number of light hours from 17hrs to 20/22/24hrs? Does it cause light stress and can trigger vegetation or make it hermaphrodite?

Grow light question
I bought a cheap light by KingLED. It’s only 100 Watts and I’m unsure if it’s enough for one plant. The light has 2 switches, one for veg and one for flower. Should I always have both on since it will be an autoflower?

Changing Lighting Schedule
The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?
