Whats up haz! Looks like your cranking out some watts there.. those look amazing. I only use one 400 and have 4 ladies under him. I love the botanicare line. Im VERY pleased with there products. I have 2 purple crack, and 2 og kush at the moment. Before i had 4 bruce banner and botanicare has done and excellent job on both grows. What is your watering cycle? How often do you run nutes? Are you on a drip? I didnt happen to catch that if you wrote it in the initial post... Thanks man, be safe...
