I have a Sour Cream (Sour Diesel x G13 Haze) Outdoor Marijuana plant. It's early into flowering now. The bottom leaves are turning yellow/wilting.. they look pretty dead... also some of leaves on top have spots/holes on them! Is it nutrient overfeed/ defeciency? Spidermites maybe (i DID see some webs along some leaves, but im not sure if they're from normal spiders or mites since its an outdoor plant and spiders are abundant in my area)? Overall, the plant seems sturdy though.. Plz help, look at the pictures, and any help is greatly appreciated!
