    i have a jm and all new growth once the leaves have reached about an inch in size
    they start to shrivel and dry up and look black,

    i give it very little ammounts of fert. when i water, i water it daily ( bonsai)

    the established foliage is doing well for the most part, none of the older foliage is showing any signs of looking like this or drying up, there are some insect damage, holes in the leaves, small, about the size of the zero on your keyboard so i don't think that has anything to do with it.

    thoughts?

    Could be frost or perhaps a bacterial blight. If it continues to occur only on the newest leaves, without damage spreading or continues to occur after frost maybe a trace element deficiency or toxicity (excess).
