on the whole the plant looks healthy and well grown but the two tone leaves aren't right.
some sort of deficiency? or maybe a virus? but seems to be to healthy for that at the moment. imo

Some of mine are looking a bit like that at the moment. I was wondering if it's the cold nights?

Cold nights, changes of temperature through the days, high winds, early warmth getting them growing too soon - could be a combination of any and all of these. Water and feeding should help. Oh and steady temperatures/low wind speeds.

Just keep an eye on them. There are viruses causing such looks, which do not make any serious harm, like, say a cold sore on a person. As long as nobody else gets it and they produce, ignore.
