My plants are currently on week 3 going into week 4 of flowering and I noticed some mildew on the leaves. I did some leaf trimming immediately to stop the spreading. Afterward, when the lights were off, I used baking soda and soap to treat the mildew. For the solution, I used 1 gallon of water 4 teaspoons of baking soda and 1 teaspoon of biodegradable soap. This morning when the lights came on, I notices some of my flower's stigmas were reddish on the top. This is my first time treating mildew with baking soda and soap so I am not sure if this is normal or not.
