I have no idea what that is and have never seen it before. Maybe you could give it a dose of epsom salt? The plant looks good otherwise. I bought an Ecuador White and a Cherub from the Parks sale but only the EW bloomed this season. They are both dormant now.

You may have to do a little detective work. Yellowing leaves can be caused by several things.
A few culprits:
Soil Staying too wet: (as the temp. cool down sometimes they stay wetter down where the roots are because their growth rates slow down so they drink less. Less water is also lost from the soil due to evaporation).

Bugs:
Spider mites can cause yellowing: You will usually see litlle yellow/brownich spots on the top of the leaves. On the bottom of the leaf you may see little red or brown dots (sometimes you can see them at all though) Some types make webs in the crevices of the viens ounderneath the leaves. They will suck the juices out of the leaves and cause them to yellow and eventually fall off. Other sucking type of insects will do the same thing-causing yellowing..

Nitrogen/Fertilizer deficiency: can cause yellowing of leaves.

Other:
Sometimes Brugs tend to have older leaves turn yellow and drop in times when less fert. is available to
the plant- and quickly replaces them with new green leaves.
Epsom salt:
You could try using this as well. It does wonders. In the winter, if you cant find it in the nursery/garden center you can still get it in the pharmacy section at walmart etc. Look around where they keep peroxide, alcohol etc. It is often cheaper in the pharmacy sections than at the nursery anyway :)
Good luck, Your plant is beautiful anyways.

Chena earlier this summer Parks had a big sale and many plants were $1.99 including Ecuador White and Cherub brugs. Whoever found it posted the link and a bunch of us bought some. I think there was only 1 or 2 people who were unhappy with the plants they received. I also got a corkscrew vine and a few other plants. I'd assume that they must have a similar sale every year. This is a link to their site. You could check it periodically. http://parkslandscapes.chainreactionweb.com/index.php

djscathie, you say they are on your pool deck. Could it be something simple like this one is getting splashed with chlorinated water from the pool and not liking it? It doesn't look to me like it is enough of a problem to worry about and if your others are getting splashed but not showing the yellow spots it could just be this particular variety is more sensitive. Try moving it away from your pool and see if the new growth continues to develop the spotted leaves.

I just remembered another thing that can cause discolored leaves or yellowing spots. Spraying chemicals like neem or other pesticides while the brug is in full sun. I did this once and my some of my brugs leaves turned yellow and started dropping. -just a thought...
