Hi, I am 16 years old and recently planted some sunflower seeds that i gathered from bird seed. I began by germinating them in a napkin, and planted them about 2 weeks ago. They are in an area that gets a good amount of sun daily, and i water them daily. I felt they were doing really good, but once they got about 6 inches tall they began to droop over. I cannot figure out what is going on whether they aren't getting enough water or sunlight i do not know. Any help is appreciated. Thank you.
