  1. there is white dust on the leaves of my plants and i'm not sure why or whats causing it. Has anyone else had this problem? what does it mean?
  2. Sounds like powder mold, but pics would help.
  3. I agree with gsxrkid, sounds like powdery mildew. Pics would definitely help, but if it is there are a couple ways to fix it. First way is to use a diluted h2o2 solution to foliar feed, but you will have to do this often to keep it under control. Another way is getting 9.7-9.9 phd water and spray only the affected areas and nowhere else. You will have to do this frequently as well.

    The best solution to powdery mildew among many other problems is to invest in an ozone generator. Just make sure that it is vented to the outdoors because ozone can cause respiratory problems when concentrated.

    Good luck!
  4. thanks guys. I think u are right it does sound like mildew powder. Thanks for the tips
    I will upload some pics soon then(when i'm not feeling lazy)
