Beginner Gardening: What's growing on my Night Blooming Jasmine?, 1 by MacFL

I have a small (1.5 foot) Night Blooming Jasmine that I am trying to grow large enough to plant outdoors. It was received from the nursery about a week ago and planted into a 16" pot of 50% Hyponex Potting Soil and 50% Hyponex Cow Manure Compost (0.5 0.5 0.5). About 2 days a go, I noticed this strange new growth of off-white spots on the foliage. I am wondering if it is a fungus or something. Anyone know what it is, and can I do anything special to make this plant take off and grow? I want to transplant it outside to my yard, but it has to get much larger to handle south FL sun first. (Please see attached photo for a look at the spots).

Thanks in advance!
