Disaster plant Critical Orange Punch

I have completely eliminated the cochineal but now I have another problem. Growth has stopped and the leaves are curved downwards. One would think of excessive irrigation but I exclude it because I have not watered it for 3 days and there is no sign of improvement. I gave her 300ml of water and she had no runoff. Could she have gotten intoxicated with the Marseille soap and oil solution? 😁 Help Due to some erroneous readings of my ph meter I watered for a couple of days with a very low ph and this is the result. I washed the substrate with a couple of waterings at ph 6.00 and it seems to be recovering. In any case there is a consideration to be made, of all the qualities that have undergone the same treatment, this is the only one to have shown such serious signs. All the other plants have resisted the imbalance well, only some leaves have given small signs of suffering .... this plant was born badly and will end worse 🤣. The cuttings: in dwc it has incredibly resisted but grows very slowly, while the cutting in the mini pot grows much faster and healthier. Update: the plant seemed to be recovering from all the stresses but NO, the new leaves have the tips and contours of the scorched leaves facing downwards. They would look like the symptoms of root rot even if it is not smelly. Instead one of the 2 cuttings again showed signs of cochineal, promptly sprayed a special product. I am seriously considering cutting down this plant that has disease resistance as a 90 😭🤣🤣🤣 year old. Dear friends of the Dutch-Passion, eliminate this plant from your catalog that makes a better impression. 🖕
