My plants are at day 22 and are growing rapidly. Im following tangs feeding schedule and currently having 500mls a day. When I water each time my pots are dry. They do seem to perk up after watering but droop most of the time. Im going to be bumping up the amount of water tomorrow. Not sure if I'm underwatering or are my pannels causing this being to close? They are at the recommended hight 24"
