Too close to light? Nute deficiency?Yellow leave with brown spots, what is going on? Showed up really in the last 2 days. It got a half strength dose of big bloom every other watering, the light was pretty close about 6-8 inches away. I didn’t check on it for 3 days so it grew a bit and was super dry.
