Setting up Ebb n' Flow SOG 4x4 trays under 4 600w HPS

Hello! I've used this website for a couple years for advise with my grows, problem solving, etc. and I've finally gotten around to making an account. As of now i'm wrapping up a 1600W grow.

The current setup:
1x 1000w ion ballast, predator XXL hood, 1000w hortilux super HPS bulb
1x 600w sunleaves ballast, hood, and bulb
Main conditioning from house cooling room/dehumidifying. (70-80 degrees) (40-50% humidity)
Hoods are air cooled, air is pulled through carbon filter and out of room.

Nutrients:
Flora series (grow,micro,bloom)
Silica blast
Liquid koolbloom then powered koolbloom for the final 2 weeks
floralicious
calmag if needed

Plants/Strain info:
8 plants, 7 now, one was harvested last week.
7 gallon smartpots, 4 pure coco, 4 coco/peat moss/perlite mix
Strains:
1x Blueberry Headband
1x Skywalker Kush
2x Treetop (One of my strains)
1x Miami H. (One of my strains)
1x "Candy" (Shit strain)
1x Fruit
1x "Apollo" (Plant I harvested)
I apologize i only have pictures of the ladies right now, none of the actual set up.

As of now, I'm expecting around a 1.5-2 lb yeild from this room. The plant I harvested last week was roughly 2.5 oz, and it was a small plant compared to the rest. If i could pull 3-4 oz from the other 7, i'd be in the range i'm looking for. But enough of my current grow, I'd love to hear opinions on what i'm trying to set up next.

For my next set up I'm going to run:
4x 600w air cooled lights
Each light will have a 4x4 ebb n' flow tray with resevoir,pump,etc underneath it
This setup will be in the same room as my last, so the air/humidity won't be a problem whats so ever.
1st 4x4 tray - Weeks 1-2
2nd 4x4 tray - Weeks 3-4
3rd 4x4 tray - Weeks 5-6
4th 4x4 tray - Weeks 7-8
I'll run each tray by 2 weeks, making a perpetual harvest possible.
Same nutrients: FloraSeries, silica, etc.

I'm currently on my 3rd grow, and i'm starting to get the hang of this. I've never tried a hydroponic system apart from using hydro nutrients and coco. That being said, these are the questions I have for the more veteran members on this site:

What medium should I use? I'm thinking 4x4" rockwool cubes on a bed of clay pellets
How many plants per light? I'd say 4x4' area per 600W light, 1 plant per sq/ft so 16 maybe?
And any other useful information in an ebb n' flow system would be greatly appreciated (:

Hope to hear a lot of opinions! Thanks.
