They are looking normal to me. not overwatered in my oponion. Maybe a bit hungry, some plants get lime green on new growth and darken up as they age. In the video it looks like some of them are moving aorund more then others. If the fans pointed at them I would change it so the fan is directed at a wall or the lights, still moving air in the tent but not stressing the plants.
With soil I find a PH of 6.4-6.8 is good. Your on the high side of that scale, May want to lower it a bit in veg to 6.5 to see if this helps yea out.
Coconut coir is also a thief it it was not buffered. I will steal calcium and magnesium and release extra potassium and sodium ions into the medium. Be sure to be feeding some CaMg into the your regime given your medium is 45% coir.
If you feeding your plants anything please update it into your journal and give a rundown of whats in the medium and how you are watering to help anyone give you better answers.
Good Luck!
