Hi Bushdktr,
Just looked at your photos and the thing that stands out most is in pic 5 we can see you/the photographer reflected in the background.
This means you are actually losing nearly all your reflected light, mirrors are the absolute worst thing for a grow room, they eat light.
I know how odd that sounds but the more reflective a surface, the less it reflects useable light.
White paint, matt not gloss is still about as good as you can get, yes there are all these fancy diamond mylars etc but just plain white paint will give amazing results, mirrors, aluminium foil wont or more to the point, the shiny side of foil is no good, the dull side is much better.
