NightOwl - Sage Scout - LED Grow

Week 10 going great. No major problems. Buds are getting big and fattening up nice. I put this plant in my homemade basket with stakes to spread buds and allow plenty of airflow. Mid week started noticing some spotting on a few leaves. I think it may be a little issue from nutrient salt buildup. Runoff ph has been low under 6.0 with high ppm. I flushed today with 3 gallons plain distilled water and got runoff Ph to 6.10 with a ppm of 445
