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.

Yellowing leaves & tips curling down on 14th day. Coco / Autopot / Hesi / Mars Hydro fc-1500
Would gladly use some help with my first grow 🙏 2 main reasons come to mind after googling: 1. I overwatered thinking it's hard to do since I'm using the Air dome. 2. Too intense light. Was checking a lot of growers that actually grow 24/0 and went for it 75% 40cm.

What’s the ideal amount of LED light for top quality in a 4x4 tent.
I’m exclusively looking to grow top end quality. Already can with HPS setup but wanting to switch. Is 480w Kingbrite LED quantum board with 385,660,730nm enough for this or do I need more? Any other suggestions? Aliexpress/Alibaba manufacturers preferred due to shipping costs.

Auto and regular plants in one box.
I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box. What should I do, keep the 20/4 light schedule before the auto plant finishes and after change to 18/6? Or change it right now?

24 hour light cycle?
How advisable is it to run 24 hour light cycle? I’m interested because I live in the north and we’re getting to winter. The light divers provide some heat. They’re autoflower OG Kush.

Light flashed on
Our power did some interesting things during the storm & the lights went on in the tent - I would say they literally flashed on & then off (along with the rest of the house) - during the *dark* period. How concerned if at all should I be about this? Anything I should / could do?

Use lamp while waiting the sun ?
Would it be worth it for me to go and buy a CFL bulb at a DIY store while I wait for the sun to come back? Or is it not good to have 2 different types of lighting (sun and cfl bulb)? And what kind of cfl bulb I could take?

ViparSpectra P600 or P1000?
I'm just starting with a small setup (40x40x100cm tent), only one small plant at the time, but want to be able to grow proper quality in long-term. I suppose the biggest difference between the two lights is the 930 vs 1006 umol/m2/s? Any advise appreciated!

Light Burn? Mars Hydro TS3000 at 30% Power, 26 inches away per manual. I have since raised back to 30 inches.
Is this light burn? I noticed some slight yellowing/crispy looking leaf at day 11. Light is about 30% Power, about 30 inches away. I previously had it about 26 inches and raised when I noticed this issue about 24 hrs ago. Pics are updated. Temps: 70-75 RH: 50-60 Soil Runoff: 6.5
