@The_Bearded_Grower, I guess. I have a lot of air flow with 3 fans on high. The humidity was only about 55% usually, except it would go up after watering. I have a little dehu in the tent but I guess it sucks. I only empty it like once a week.

@Ezzjaybruh, thanks for your comment! I'm using organic Grower's Ally Fungicide Concentrated. Used 3 tablespoons with a gallon of water in a Vivosun Sprayer, and it was enough to cover all 4 plants making them dripping wet. Next day no mildew on leaves and did not come back. Some of the deep lower foliage sugar leaves mildew still stayed, but I tried not to oversoak the buds so that's my fault for not hitting those areas enough. I'm very surprised how well it worked with only 1 application. It did turn all white hairs brown though, but buds are still growing and producing new white hairs the next day.

@JabzXtreme, Just wandered my way through your journal and I must say I'm pretty impressed! Seems to me that you were pretty ambitious going in and that its really paying off for you. Looking forward to seeing how your harvest results turn out. Best of luck!
