I have a fukien tea that i purchased at the begining of the year and has done well all year until last week it started looking like this. Since its in organic soil ( some coconut husk mix i found) im careful to only water it when the top inch is dry. I feed it a 20-20-20 fertilizer every time i watered which was every week to week and a half. It has been raining quite a bit here the past few weeks and im wondering if its just getting too much water.
