I've posted in the problem section about some white stuff I have seen on one of my week or plants that hasn't been developing. Today I noticed something White on one of my healthier plants. I'm worried it's mold or mildew. It was suggested to spray with 99% alcohol? If it is mold or mildew does anybody have any other ideas or better ways also I wonder if your supposed to spray the whole plant? That doesn't seem like it could be good for it. Here's some pictures from both plants. The darker leaves with the bigger patch of white is the weaker one and the lighter Green Leaf is the healthier one that just had it appear today. It was recommended to me to stay with the humidity is high as possible. I've only managed to reach into the seventies if I'm lucky and use boiling pots of water outside the tent. They usually stays in the 60% humidity range or high 50s. Usually stays about 75 to 79 degrees.
