I do hand watered hydro in plugs. I used to use GH micro grow bloom, till it became hard to get and now I use GP3 micro grow bloom which has identical ratios. I also have a 5L bottle of 12% H2O2 and I'll splash about 10ml of that into a bucket of nutes.
Using Micro:Grow:Bloom in that order, I...
3 Master Bruce from The Night Owl. bruce banner#3 F3 x blue power F4, they maybe have even outdone the Blue Powers in the frost dept, and do not have the genetic problems of the BP. Will go for another week and two weeks for the greenish one which was always a week behind for some reason.
For a 6 x 2, three Viparspectra xs1500 pro would give you a perfectly even coverage, using 150W each. I'm using 4 of them in a 60x32" with an open side and it's overkill but it gives me more flexibility.
I ended up getting four, and now I'm getting more light in my open sided tent using 400W than I was previously using 550W, and given the right genetics they definitely do the job.

There is also Shallow Water Culture too. Where the roots come out of the net pot into an enclosing pot with a small pool of water that overflows into a res. This also allows the roots to absorb the shallow pool and sit. Using the Nutrifield Pro Pots.
I would suggest giving the large Eazyplug pyramid a go. You’ll only need to water twice a week at first moving up to three times a day.
i do it all by hand but you could set up automation but for me that defeats whole purpose.

FFIW, I just got rid of my two QB96 running at 180W each and two other 100W lights and replaced them all with 4 of the new Viparspectra xs1500 with the lenses. I was going to put three in my 5 foot by 32 in tent, ended up with four. And boy oh boy what a difference. Instead of 550W I'm now using...
If you don't want to knock the N down a bit then FFS you need to do a shedload of defoliation. I mean what is the point of dark green leaves sitting in the gloaming of the undergrowth.
