Powdery mildew possibly? Spray with diluted hydrogen peroxide
Esteban1 Reviewed by Esteban1 on . Powdery Mildew, Spider Mites and Thrips. AAAAH Hello, So two/three weeks ago i noticed some white dandruff like powder on my plant leaves. They started on the lower leaves and worked their way up. I thought it was powdery mildew until today when I noticed stuff on the underside of the leaves. I had sprayed them three times with milk and baking soda and a little bit of dish washing liquid soap. I bought cannacure (CannaCure Spray 750ml Spidermite Pest | eBay) yesterday and sprayed them, but they look worse today than they were Rating: 5
