Rose leaves bleaching or turning purple
About two weeks ago I repotted a supermarket miniature rose (a red Kordana) into 4 separate pots, one for each plant. They looked much happier and starting growing new leaves, but now, some of the growth is starting to look a little strange.
The leaves on top of the plant are turning white - but it's not like mildew, more like the leaves themselves are bleached. The edges of the leaves are a dark purple. Some of the oldest growth is also starting to curl up. I gave them a little fertilizer a few days ago but I can't tell if it's helping.
Has anyone seen something like this before? You can see the effect on the upper leaves in the photo, compared to the leaves on the bottom of the plant.
