Northern Lights Auto #2

The plants have had excellent growth this past week and I've had to drop the plants to the ground and max out the height of the light. By the end of this week the plants are around 30 inches tall and are inches away from the plants. I have run out of pH perfect nutrients and switched to Hygen Coco. They seem to be working well and I have still not spotted any deficiencies. I have started defoliation, removing a few leaves every watering to open up light to the bud sights. The FL and BR have lots of high up colas compared to the other two plants which have colas lower down, not getting much light. The modified setup with the extra dehumidifier and the diy CO2 seems to be doing it's job with the humidity around 60% constantly.
