I had a very similair looking problem with a few of mine but i just used normal soil from the ground and the roots couldent spread and it held to much water i would say transplant it to some good potting soil and should help fix that problem
BayAreaTrees Reviewed by BayAreaTrees on . Insect and/or too much water ???? PLEASE help Here is my setup: -Plant grown outdoor -Made a big hole in clay as it is all I have where I can grow the plant and filled it with ProMix BX and a little Bone meal. I was afraid clay would retain too much water so I inserted a pipe in the bottem of the hole as shown on the first picture. - Noticed 2 weeks ago that the plant had small holes in the leaves but did not make a big deal out of it. - Plant has lots of holes in leaves.
