Swedish Ivy veins on leaves turning red

Oxford, United Kingdom

I have a large Swedish Ivy (I think it's called that - we call it a money plant in South Africa). It could also be called Plectranthus. Anyway I have taken a number of branches off over the last few months as it is getting old. I put them in water until they grow roots and replant. They start off beautifully, but over time the oldest one has started getting red veins. See the photos below. I planted the newer two about a month ago. The older one was planted about 4 months ago. Why are the veins going red and how do I get them back to pure green?

I found this explanation by jonivy.
"When grown outdoors and temperatures approach freezing, anthocyanans are activated. Veins in the leaves of Plectranthus verticillatus turn purplish-red, giving it a completely different winter color scheme."

I found your same question was asked here in 2006. Towards the end of the thread it was suggested that too much light or soil lacking nutrients may cause it.

Thanks, I can see how temperature could have been the cause. I wonder if it will get back to normal when summer comes or whether I need to add some nutrients and what those would be?
