I just tuned in today on what you're doing. Looks great so far. I have been working with 300w LED Panels for a year now and I am enjoying the results. I have evolved to the point of putting them on Light Track 5's and move 4 - 300w LED panels over a 4'x8' tray about an inch above the canopy (sometimes touching). If you're interested I will show you pics of the great results. I also had a similar problem with the leaves bleaching out, it turned out to be a nutrient lock out. I remedied it with an amazing product called Sea Green.
I have been using many different panels with different color combinations, so I am very interested in your blue dominate experiment. I am working with a new company that will make me any combo I want so I'd like to learn any color advice you may have.
