You know these cheap metal stands you use to put hot pots and such like on so you don't burn the table/worktop/whatever? Get one, sit plant pot on it, gives more breathing space and allows water to escape.
Saw the previous pics, thought something might be up but wasn't sure if it was N deficiency or natural for that plant. Spots and so on could be Calcium, or lack of, tips could be over feeding, better pics in natural light may be best but if you're saying things aren't draining and have turned to mud then the roots may be gone, pH out of whack, could be quite a list of things.
