Light doesnt cover every pot
So i've got 2 plants under one cfl lamp and i observed that that 1 girl is reclining to the right. As i see my Cfl this girl is standing right below the plastic part of the cfl and obviously gets less sun. How can i fix this? Changing place my pots every day will do the job?

Is closer to the light much better?
Is the light closer better? I have a VIPARSPECTRA 1000W LED Grow Light (10W LED ,x100) and it says during veg 18-26 and flowering distance at 18-24”. Looking at other growers using LED they are closer. Should I try to keep it closer a little at a time? Is there benefit?

Are IR cameras dangerous for the night cycle? I have my plants on streaming and I'm thinking of placing an infrared camera and IR LED I'm worried that the IR light can stress the plants and interrupt the night cycle. Wave you experience this with security cameras?

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.
