Hi, I have bought passion fruit from a shop and planted the seeds, they have all grown quite fast up to about 4 feet tall. However, some of them have developed what looks like a disease where some leaves have turned pale green then white.
I asked why this had happened at the garden centre, but they were not sure why this had happened.
-They are kept warm, well watered, maybe I have given them too much fertilizer?
Any help or ideas will be greatly appreciated, thanks!
