powdery mildey? plus leaf issue

[SSDIPainGuy]

Can you just blow the mildew off the leaf or is it kinda of stuck to the leaf? I have a lot of white dust on the leaves, couple of plants, but it blows right off. I did install a new light so maybe drywall is falling a little. In the pic, leaves are very curled down, like an upside down taco. Deficiency? Where are ya cat? Lol295780

I don't remember from your previous post if you have any airflow going on with your grow, but if not then you need to do this. Airflow is one of the most often overlooked issues with an indoor grow. If that's in a bathroom, running the fan along with a floor fan might be a good idea. Whatever you use, air has to move in and out of the grow space for most of the day to get moisture out, which is probably causing the powder mildew and you also need to bring in CO2 from outside and moving air also helps with temperature control.
