White Mildew

[mb420]

My girls are about 7 weeks into flowering. Noticed white powder on leaves about a week ago. Is it a total loss or can something be done to cure them? Should I harvest now?

1cup hydrogen peroxide 4cups water. swoosh it around for a few minutes, dab it gently with a towel and/or fan dry it ( per Jorge Cervantez). I did it with a flowering plant and it worked perfect.

Mildew is caused by high humidity & poor air flow through canopy of plant.

> 6 inch fan inside tent/grow area will improve air flow in/around canopy.

> Suitable ventilation or even a dehumidifier may be of an option.


Its not a good sign at that stage of flowering as it may lead to other molds forming.

Along with the peroxide, you can use milk at a rate of 1/9 or one cup of milk to nine parts water. Neem oil works well also, use 1tsp per liter, add 1/2 tsp dishsoap for an even disspersal. Keep an eye on them and hit any areas of re-occurence as it is hard to get rid of once infection occurs. Powdery Mildew will cover your foliage and reduce photosynthesis and thus growth and last but hardley least, yield. Do not spray within three weeks of flowering, hope this helps...
