Shasta daisy problem
I potted 2 Shasta daisies in large pots a few days ago. One pot looks great, but in the other one the plant had wet looking dark, clear patches on the leaves and some new buds are withering. Now the spots are dry and brown. They have the same water, soil and sun exposure. I'm in Orlando, Fl.

This might be a fungal disease, such as those described under "Chrysanthemum" in this article:
Removing and discarding the affected leaves might help stop the spread. If the spread continues after that, removing the affected plant to protect the healthy plant might be the best option.
