raise lights during stretch?
Should I raise the lights during flower stretch to maintain the same distance from light source to canopy? I notice that my plants continue to get taller than most. I know the stretch is natural, but I'm wondering if constantly raising the lights with growth is the right approach

Light setup
Currently I only got 2 x 50W / 5000K flood lights for veg and approx 150W / 2700K later for flowering. Both LED. Planning to keep lights close to plant - 35-45cm. Do you think its going to be sufficient or should I get professional lights asap?

Are there any recommendations for a light schedule for autoflowering?
I leave them at 24 hours. I start with the seedlings at 18000 Lux and increase it till the 4th week. After the 4th week I have all my lights at full power and the top buds have around 55.000 to 90.000 Lux.

Distante between LED and plants.
The distance between the LED and the plants is 53 cm. Is it ok for the first week? I've read that a short distance in this stage is good to produce a not so tall plant.

23 hours light per day?
I’m running 4 autos in a 4x4 tent on 20 hours of light per day. I’m thinking about the possibility of changing the light hours to 23 hours a day and 1 dark hour. I’m currently on week 8/9, I’m expecting it to finish roughly 12/14 weeks from birth. Any thoughts on this growers?

Light source change stress?
Can changing light source cause stress to your plant? Yesterday I changed from a CFL to a 150w Mars Hydro LED and this morning she looked a bit "sad". I took the photo straight after watering hence the damp soil.
