Help! bottom leaves are turning yellow

This is my first time growing and the bottom leaves are turning yellow. Not the first set that naturally dies off but the next set. I have heard not to clip these because they are important in the flowering process. Can someone please tell me what I should be doing?

you should be reading the faq's instead of starting a thread in every forum on this site.

you should feed them nitrogen.

1. Don't post in every single sub-forum
2. Feed them, probably have never been fed. The soil can only do so much.
