At first, you are choking her with that strings at the base of the stalk, than you have got disease some kind of fungus and most likely also spider mites or similar funky staffage. I guess you either do something about that and pretty fast or you will lose the plant sooner or later. Citric may help with pests as well as fungus, just do not use neem anymore since you might be just helping that fungus to spread and than hold place. I would also clean dead leaves out of your soil and check it for proper moisture level, since the soil looks kinda dry and it also looks like just classic bagged potting soil. If so, you really want to keep it moist.
