You gave it 10% nitrogen, 10% phosphorus, and 10% potassium. I don't
really know your soil, so I will have to guess.
Nitrogen often promotes leaves and stems at the expense of flowers. It
should be used only once, at the beginning of the growing season. If
there is still some growing season remaining, a light dose might be
applied again after all flowering is done.
My soil usually has sufficient potassium without adding any fertilizer.
Phosphorus promotes flowers, but it does not disolve. It must be placed
in the planting hole before the plant goes into the ground. That way,
the roots will find the phosphorus. Putting 10-10-10 fertilizer on the
surface of the soil merely wastes the phosphorus.
My suggestion is to buy a bag of bone meal or superphospate and a 3-foot
length of 1/2-inch steel rebar. Poke the rebar into the ground as deep
as it will go about a foot away from the plant and wiggle the rebar to
increase the size of the hole. Fill the hole with bone meal or
superphospate. Repeat, making a circle of 3-4 holes around each plant.
For older and larger plants, you might need a circle of 4-6 holes about
2 feet from each plant.

Morning glory grows best in full sun on a rusty old fence in lousy
soil in vacant lots where no one gives them a fig of care... my
suggestion is to leave it TF alone before yoose kill it with a barrel
of toxic chemicals and a mountain of stupidity. And if yoose gotta
water it best is first thing in the morning to let loose when your
bladder is about to burst... why do you think it's called morning
