I have turned up the blower and increased the air flow. Humidity has been as high at 70%, but has dropped some over the last week. This is a Berry Bomb and I have two in the last stages of flowering. They are at 10weeks since flip tomorrow. It's not present anywhere else on this plant, and not on the other matching clone plant. Difference is I was doing a comparison grow with nutrients. Using MegaCrop on this one.
