I would need your need to better understand what's wrong with my Peperomia plant.
To give a bit of background: I bought the plant 2 months and everything was going smoothly. Three weeks ago i went on holiday for 1 week and I have used some sort of 'irrigation system' that was supposed to give water in a controlled way -- of course it didn't work and all my plants were over-watered. Secondly, after coming back I saw some small black insects in the plant and I thought that they could be aphids, sucking sap from the leaves. I already sprayed a solution of water and soap and I haven't seen any more insects (at least alive and moving).
Today, the plant has brown spots all over and two/three leaves have fallen. I have checked the roots and they seem fine and not rotten.
