Help Wanted

I see several things going on here. It looks like you might have a powdery mildew issue and either a pH or calibration issue causing some lockout or just a simple lack of magnesium and probably iron. The interveinal stripes on a few leaves point to that. The curving/cupping of the leaves and super pale new growth are clues. You might check out the growweedeasy site for help on how to identify and combat basic problems. They have a lot of photos to help you figure things out and solid advice on how to combat problems. It’s a great site to study and learn from so your can ID issues early on and the advisors are folks that most of us trust, like Nebula Haze.
