I recently ordered some cacti cuttings about a month ago, one came potted the other 2 were unpotted. The tops of two of them are fading to light green and losing spines (it appears). I think they are losing health. Any ideas to bring these cuttings back to life or if this is a part of them growing. They are of the trichocerus (think that's how its spelled) family are are order from sacred succulents so they are not the run of the mill peruvanous. Thanks for the help
