Star Jasmine-Is this a fungal disease?

Hi,
I planted this Star Jasmine in a large pot to climb up an archway (it wasnt possible to put it in the ground due to location) It seems to be growing nicely and starting to flower but i noticed a red spot on a couple of the leaves a few weeks ago and now it seems like all the leaves are getting them. I read about a fungal leaf spot disease and wondered if this could be it and if anyones dealt with it before/can i treat it with something? I dont really want to carry on letting it grow up the arch if its going to keep getting worse then die off
Thanks x

Also - have you potted it using a loam-based medium (eg John Innes no 3)? Multi-purpose compost dries out very quickly, whereas if you have a mix of JI no3 and MPC, it retains water much better.
Hope this helps.
Star Jasmine is a very thirsty plant and needs to be kept moist especially if in a pot, during the growing season. Scale insects often appear too when the plant is under stress.
They're also hungry plants. A feed of tomato fertilizer about once a month during the growing season will help as would an occasional feed of seaweed extract to keep it healthy.

Knowledge is knowing that a tomato is a fruit.
Wisdom is not putting it in a fruit salad.
My inclination is to say try and repot into a mix of JI3 if you can - it will be easier now before the plant gets too big!
JI3 is quite heavy though, so I'd mix in some of the compost you already have in the pot to lighten the JI3 which will give better drainage
About 75% JI3 and 25% of the MPC you have already

You may find the pot isn't big enough long term though. They want to get big, so you may need to rethink how you have it planted.
