I started a Girl Scout Cookies Extreme autoflower (12/9/21) in a 1/2 gallon fabric pot as a winter experiment. Plant has looked good and reacted well during the whole grow until recently. I've noticed some white spotting on some of the leaves. Does anyone know what this is and how to correct. Freaking out a little bit because we're only a few weeks from harvest. Any insight would be greatly appreciated.

Thanks for letting me know what it is. Before I cut anything off I'm gonna try a remedy I just found. Wipe the leaves down with tap water and spray - under lights - down with 1 part milk and 3 parts water. See if that has an impact, if not . . . oh well.

I've used milk spray successfully on veggies like zucchini but outdoors the climate changes all the time so you usually only have to beat it back once. Indoors the problem is worse because your climate is presumably more stable so the conditions for pm are constant.

I even tried a product called Doktor Doom spray and it always came back. I thought I had it licked but nope. My issue was lack of airflow. It started right beneath an 18" wall fan and spread from there. I ditched the big fan and went with several smaller fans. Now I treat all my plants with Regalia once a week and don't even think about PM.

I understand silica is a good preventative as well. I have never had it indoors. Pm that is.

Wind is the best.

@manfredo suggested that. as part of your PM control too. I use silica for the first couple hand feedings. I don't like how it behaves in a drip irrigation system, causes clogs in my experience.
