I am on my second sunflower and it's starting to flop like
the first one. This one grew straight up, presented a nice 12"
bloom and reached 6'6" in height. The base of the stem is
1" wide and goes to about 5/8" near the top. It looked good
for about a week but now the flower appears too heavy and
is bending. Is this common or could there be a deficiency in
something?

Once the seeds set in the sunflower disc, the flower nods over to
protect them from the rain, etc.
