Direct comparisons are what the majority of the industry is afraid of. They don't want their product evaluated in how it compares to someone else, they want it simply evaluated as to whether or not it can grow plants (which just about any light can), or what the umol/joule is. I do look great in heels lol. I have never run coco personally. I heard from many a hydro store owner how finicky it can be, especially in regards to nutrients. LED plants tend to do better with lower ppm of nutes compared to HID plants. They also use less water as they don't transpire as much with the lack of infrared heat. Some people don't adjust their nutes down when switching to LED which can cause issues. I always recommend people use no more than 3/4 the amount of nutes they normally put in for HID or CFL. If the plants show no signs of stress or over fertilization, you can step them up gradually. You are correct, our lights are not "Blurple" although they don't look purplish-pink from outside the room. When you get up close and personal we have a customized color temperature of white where the plants appear in natural color. You can see deficiencies, pests and even take pictures most of the time without filters. We use RGB to create white instead of various phosphor mix coatings over blue LEDs. The problem with all white LED grow lights that use blue LEDs, is that they have far too high a percentage of blue in the spectrum for proper growth. This tends to cause morphological stress responses in the plant. If you look at the NASA study results posted in my other thread, you'll see that the higher you go with blue in terms of your overall %, the lower your yield and longer your cycle becomes. But from the sounds of it, a lot of members here are not keen on trusting research published by NASA. I on the other hand based our G4 spectrum on their research. I don't know who Victor or Stephen are lol. I'll get you 4 of the 84X for a 4x4 area. Put them against whichever HLG light you think is best. I'd rather take down their best than beat one of their lesser products.
