Your plant could also be rootbound. It looks like iut's in a really small pot. Transplant if root bound, and before you put into a new pot, take a butter knife and slice through all the roots. That cuts the bound roots and gives room for new root tips to develop.
Well i have re potted my plant, Now it was not restricted to the pot size it was in, i did not free up the roots when i re potted (last twice ) and the root ball was restricting itself to the size of the first pot. I have freed up the roots and gave it a larger pot, hopefully it does not die now lol.
Just in case of death i have planted a new seed to grow beside it.
