Second grow, I replaced a blurple with an HLG-120H-54A. Plant is growing much better but I am getting brown spots on the leaves. I have had trouble with heat but it is now staying btw 25-30C.
Now I am getting brown/orange spots on some of the leaves. I thought it might be the light, but the spots aren’t on the top leaves. I have a compact setup, so my light is ~16-18" away from the plant. My light meter registers at around 1000 at the top of the plant.
I assume this is either a light problem or a Nutrient problem? I am using Dr. Earth 2-2-2 fertilizer and watering once a week with it.
