Q.weak plant
My spider plant was very blossomed but now it comes out weak. It has babies but they are dull and yellow. What should I do and how can I re-blossom them?

If the mother plant's leaves are green, all is well. Just give the plantlets time to mature. If the mother plant is pale or yellowish, or has many brown tips, you might need to leach the soil well (run alot of water through it, about 5X the volume of soil) to remove extra mineral salts. You could also try repotting, washing out the old soil and using fresh (I like 50 - 50 mix of cactus potting soil and perlite.) Alternatively, if you haven't fertilized in a year or so, some balanced fertilizer is due. Spider plants don't produce flowers and baby plants until they are potbound, so it may take a year or two after you repot before it starts bushing out again.
