pineapple express x2 and banana kush

Everything looking great. Another new light installed because the coverage from the Advanced Platinum Series P300 300w 12-band LED Grow Light was not where it needed to be with these plants. I installed a Advanced Platinum Series P600 600w 12-band LED Grow Light - DUAL VEG/FLOWER FULL SPECTRUM in the back of the tent over the two Pineapple Express plants and the P300 300W is over the banana kush. Total of 900W led in the 4'x4' now. Light schedule switched 12-12. Plants have been very thirsty. Sometimes watering twice a day 1.5L at a time per plant. Still following bergmans feeding schedule feeding once a week. I also have been defoliating weekly.
