My plant has a yellow burned spot

theres two spots on two leaves that are yellow n brown im wondering if i should clip it its the bottom of the leaf and in the middle its yellow brown burnt looking and on the tip its green every morning my plant grows new leaves and is getting taller and more leaves that are bright green healthy but im just wondering what you guys would do and sorry i cant upload a picture cause this library computer wont let me

And one more question my baby is still vegetating i give it about 9 hrs a day with my cfl's and in the night i put it in a cupboard and close it i was wondering even when the plant sleeps does it still need a FAN HITTING IT???
