Hello, I'm growing 4 plants in a 4x4 under 4 QB96s. The highest lux on the canopy is 17,000, which shouldn't be too much for mid-level veg plants. However, they seem to be showing signs of light burn. I've pH'd my water to 7 and the potting soil is Happy Frog with good super soil, so I don't think this is a pH issue. Also, I've been foliar feeding for 3 weeks with Calimagic in case it was a mag deficiency. Anyone else think this is light burn? Thanks!
