It might have been the move, Arran. Any drastic change in Pachira's environment will cause it to drop its old leaves, and grow new ones more suited to its new home's light and temperature regimes. I would double check the light levels, because this effect is exacerbated by lower light.

IME, smoking isn't good for any plant, though some can take it better than others--it wouldn't surprise me if Pachira turns out to be one of the more sensitive types!

Thanks for your reply, Ive put it in more direct sun light and yes your right it is growing new shoots, poor thing looks like its just joined the Army and had all its hair shaved off ! , where i had it before was in a corner with light but not as much as it has now , thats why i moved it, and plus ive changed my Fig to that place as my Fig was losing its leafs where it was so thats been moved 4 times and is now happy growing new leafs in the corner where the palm was , God i get one plant happy and then the other complains !! God their like a married couple lol, Thanks again for your reply, fingers crossed it will survive and get stronger,
Thanks
Arran
