I did a small side-by-side comparison (originally a test to see how much I could increase the daily photoperiod before seeing negative effects). These plants were all leaf-pulled clones from the same plant. Three cups on the right got weekly waterings of azoxystrobin (Scott's DiseaseEx added to distilled water until 100 ppm). Two cups on the left got normal RO water.
They are have been getting ~22 hours of light per day for 2 months. Biggest difference is that the untreated plants had more blackened traps. Every plant looks worse than it did at the beginning of the experiment, but this was a weak cultivar to begin with. A better test would have a much larger sample size, with multiple different cultivars.
