Hi Leda, So glad you found us here!
Leda, have you taken your spider plant out of it's container to see if it's perhaps root-bound? One problem I used to have with Chlorophytum is they grew so fast and filled the pot with roots that the root system could no longer take up the water and the roots died. I've never been able to keep spider plants looking good unless they are planted in the ground in bright shade! I can't begin to count how many hanging baskets of spider plant I've had over the years! They would look great for a little while and then the leaves ended up getting brown edges and the plants just looked downright ratty! One time I had one hanging in a tree in the backyard where a few babies fell off and took root beneath the tree ... those always looked really great so I just decided they must prefer being in-ground rather than in hanging baskets. I have a non-gardening friend who had spider plants as a ground cover in a spot in her yard and they were always so pretty!
Chlorophytum (Spider Plant) somewhat resembles:
Creeping Lily Turf (Liriope spicata 'Silver Dragon')
Monkey Grass (Liriope muscari 'Variegata')
I think the flowers of Liriope are much prettier and the plants are much hardier as a ground cover in most areas. I've lost a few spider plants to freezes over the years but they are so easy to come by and always abundant in local garden centers.
