Hey gang! What kind of deficiency am I looking at here? I thought nitrogen since it’s starting with lower leaves but I’m not sure.

@Mr. Grow It definitely getting worse. It used to be the lower leaves but seems like there are more leaves affected each day. Following my idea that it might be a Phosphorus deficiency, I just watered with a Boost Tea (from Earth Dust Nutrients). One of their emails mentioned that it was a way to deal with a deficiency and since Boost is higher in Phosphorus, I figured i’d try it. I’m also trying to remain patient, as a new grower, I’m still learning the rhythm of organic growing.
