I've never grown sunflowers but yellowing leaves usually indicate a watering problem or soil issue. If your watering regiment is good, then look up common soil/nutrient issues with sunflowers. In my experience, the problem plaguing my plants is usually the first thing that pops up.

that's really helpful, thank you! I'm thinking it might be over watering but I'll check on the nutrients too
