Distance, lst and # of plants

I have 6 mars hydro ts1000s. Spaced about 10-12 inches apart. As of now I have 8 plants and the fixtures are about 12-15 inches away from the canopy. I am 4 and a half weeks into flower and I was wondering a few things... Should I move them closer? What should my ambient and leaf surface temps be... in the future how many plants could potentially be flowered under said "6" lights?

The question isn't how many plants under how many lights, the question is how many square feet of canopy you can grow, at the distance from which your lights create and even PAR footprint.

I grow in a 4x4. No matter if I have 1 light or 10 lights, I will always be at 500 watts. No matter if I have one plant or 10 plants, my canopy will always be 4x4.

Holy shit. Why aren't you feeding your plants? You know plants are supposed to be green and not yellow, right?

Please give more details about your grow OP, those plants are not well and the reason isn't down to just the lights. Give us some basic info on your media, nutrients, EC/PH, feeding frequency, temps/rh, etc. You mostly likely have several overlapping issues going on right now that were exacerbated during stretch. In the meantime, I would raise the lights up a bit-less light intensity will slow down the deterioration until you figure out what's wrong.

The reason behind the deficiency was a double flush. I was under the assumption I was dealing with a lockout and wanted to start fresh. 2 days later bam. They were in serious need of nutes.

My lux at 12 inch from canopy to fixtures is around 50-60k. Ppms are about 900-1000. Ph is around 5.9 to 6.2. My leaf surface temperature is around 77°f with ambient temp of 79°f - 80°f and a RH of 50-45%. I feed every other watering since the "flush" flush that brought on the yellowing.
