Replace often scant irrigation to a rare, but abundant, full irrigation of all soils.
If more glaze rare not helped to get rid of mold in the pot failed, transplant the plant in a pot smaller (if you see that the roots occupy only a part of the land). You can do without a full transplant, just replace the top layer of soil in the pot.
