It certainly could be that there is some leaf curl problems, but it looks a lot more like mineral deficiencies to me, now that could be simple the soil itself or could be related to the root system of the tree.
If its the soil thats relatively easily fixed with regular applications of trace elements through your watering can, try the simple basic approach first before buy and applying anything powerful to knock out fungi etc...
The site Ekka put up is most excellent and I would definately put that one on your favorites, if you look at the various documents relating to peach leaf curl you'll see whilst there are strong similarities to the curled parts of the leaves on your little tree the colouration in your leaves is quite striking, regular and intervienal, cholrotic. However since you write that you have added nutrients I suspect the problem relates to trace elements, and this would be common in very sandy soils.
