well i kind found out whats wrong, the plant was just recently transferd to a bigger pot and more soil, but i pulled out the whole root and surrounding soil out of the pot today and i discover that the roots have'nt brake through to the new soil, i shed some of the old soil off the roots and replanted it in the new soil while the soil was still moist and gived it a little water, so now all i can do is wait and see if it comes back, i hope i did the wright thing, any advice is welcome, THNKS.
