Banana Kush auto isn't happy

Any idea what's going on with this plant? Doesn't need water and the P.H is between 6,5 and 7
My other plants are fine - they aren't autos

What are you feeding it and how often? temps and humidity? is that the ph going in?

What's your medium?

Its a mix of Fox Farm Coco Loco and Fox Farm Happy Potting mix - roughly 1/2 and 1/2
I'm feeding them Fox Farm Grow Big as per instructions. Today i gave her straight water and the rest the Grow - she looks a little better not as droopy but i'm wondering what those spots on the leaves are all about.
