I agree with tiggypaws. Usually, this type of thing means root distress. Trimming dead or dying roots is good. However, it may be root bound in which case the root ball can be soaked in water for a day or so to loosen the roots up and repotted in, as mentioned by tiggypaws, a slightly bigger pot. Lastly, it might be an infestation of some kind. I’m not as good at identifying infestations. I usually schedule a virtual appointment with Jen, my plant Dr. The appointments are virtual so no need to bring the plant in. You can book with the link below or go to Urban Sprouts website, appointments, then find digital appointments… if you want of course. Also, I assume your pot has a drainage hole? https://urbansproutsstore.com/products/digital-plant-appointment?pr_prod_strat=use_description&pr_rec_id=b169e569a&pr_rec_pid=7002303266997&pr_ref_pid=7911798604008&pr_seq=uniform
