Cheech Biggums + Space Station Orange

Almost all the fan leaves are dead/faded yet <5% amber trichomes. I’m gonna chop this week. Unfortunately I noticed some powdery mildew on the Lower leaves of the cheech. My humidity is 35% and 70F tent temps. I think the problem was I turned the cloud infinity down from 3 to 2, and this reduced the air circulation too much. Gonna leave it at setting 4 for all future grows.
