Did a lot this week. First FIM on largest plant, at the 5th node. Maxed out the light to 100%, was at 50% from day 1, and slowly added more light each day. Added a touch more nutrients and enzymes to aid in root health. PH is down to 5.8. Plants are doing well and growing very fast. With the lights a little closer and brighter they are no longer cupping or stretching for the light. No signs of leaf tip burn.
