Come to think of it, that probably explains why my Korona app has been having a hard time with accurate readings in the auto tent since I added the quantum board. The app is designed so you pick the type of light you're measuring, like "full spectrum led" or "red and blue led." There's more, but those are the two relevant to me so I unlocked both of them for $5 each. In the photo tent it reads perfectly accurately. And in the auto tent, when it was only blurples, it also read completely accurately. But now in the auto I guess the app isn't sure if it's reading red/blue or full spectrum, and as a result the readings fluctuate all over the place. I'm going by eye/experience now, and last night I raised the light a bit to accommodate the Pineapple Express' that are still stretching out. Tomorrow they will all get hit with a good dose of Cal Mag plus Iron, as I am getting a few yellowing leaves and rust spots, and the new growth isn't quite as green as I'd like. They should be firing on all cylinders for the home stretch after that.
