Yellow Leaves!!!!!

Hi everybody,
I'm a first timer and everything was goin great till I started gettin some yellow on my leaves, And as u can see in the pix the bottom leaves r dryed up while the rest of the plant is fine. I've already tried some of the stuff suggested here but it doesn't seem to help. Can anybody else give an opinion?
Thanx

I would love to help but I am not seeing any pictures.

mine is yellow too was bout to make a new thread related to this. also please provide what food should we give it. how much. and a picture of this food so we know exactly wut to look for at our local home depot or walmart.

What all have you tried doing?

I'm sorry It looks like the pix where not uploaded I will try to put them up again ASAP!!!!
