Thanks! I’ll check the PPFD. I already have Cal/Mag in the mix and I buffered the coco with it before starting. I know you can increase the Mg with Epsom salts, but I haven’t found how the suspend it at what strength before adding it to the water/feed.
This light is really bright at half power and it’s over two feet above the tops of the plants. If I have to turn it down now, I can’t wait to see how it does during flower.
