Hi there, A cannabis phosphorus deficiency generally appears on leaves from the lower/older parts of the plant. The lower leaves may turn dark green or yellow, and start getting spots or big splotches that look brown. Sometimes accompanied by a Calcium deficiency, as Phosphorus and Calcium interact with each other in the plant.
