I have two young tissue culture kiwi plants and these photos are from last year. The brown area on the leaves eventually spread to the entire leaf(s) and they all died(just the leaves, not the plants). There also seemed to be something white mixed in as the leaves deteriorated. These plants started to grow back this year but the same process is occurring at a point where the leaves are much smaller than those in the photos. The leaves are all dying again, but the stem is still green.
The plants are in containers and under fluorescent T5 grow lights. I try to keep them well watered but I don't know if this problem is caused by a disease or too much water, or too little water, or too much light... has anyone seem this before?
