First time grower- just started flowering phase. All plants are all healthy except the plants nearest the air intake are dark green and taller than the other side which are shorter and lighter green. the internal fan is in the center, so i was wondering if the right side of the box isn't getting enough fresh cool air, thus the difference. Or, is it that direct light is too much for them; the left side has less direct light becuase the light shade blocks it a little. Any help wise ones?
