I'm new to Bonsai trees, and recently bought my first one. Although after about 15 days the leaves have begun to fall off, and there are strange white web-like spots on various branches, and I'm not sure what to do about it. (Also, in case anyone's wondering, I am buying a new pot to replant it in, as well as proper soil and fertilizer within the next week, the current pot is the one it came in, and I am aware thsat it isn't ideal)
