They are really loving the additional 300W of LED light. They are stretching up tall. I also removed a good portion of lower leaves and sucker branches to allow a little more air into the stand. Still doing 3 tsp of Fox Farms Grow Big and the end of last week i flushed the plants with Fox Farms Sledgehammer.. and continued my feed as normal. Had to place the white queens on crates to keep all my canopies even so i can bee both LED arrays even.
