The dreaded Powdery mildew, which may be out to ruin your crop.Just went through it sorry and I hope I'm WRONG.Peace Showgirl

any remedy for it?

come on people, help me out!

Sounds like white powdery mildew. A sulfur pot would help a lot. Increasing airflow so the mildew can't settle and reproduce an also help. But I would say the best solution for mildew is a sulfer pot.

When the sulfur pot is used properly it will leave a slightly acidic coating from the sulfur on all the walls, leafs, any surface in your grow room. Mold and mildew cant settle or reproduce on this slightly acidic coating.

Be careful though, when sulfur pots are used Properly they work great and wont affect the taste of your crops.

Any fungicide will do. Hurry before it destroys your girls though.

^^^ Yes, spray them down with fungicide or neem oil fast, a sulfur pot is better for long term solution
