I wouldnt get all worried about the bottom leaves, the ones at the bottom naturally gets old and fall off, it's the mid and top part you should be concerned about when they turn yellow, or maybe it is important. Pics would help.

The leaves toward the bottom are important, they are the first to be used up if the plant lacks any essential elements. Discolouration at the top of the plants is due to over fertilizing or other factor. Its best to monitor the bottom leaves carefully because they will tell you first what your plant is lacking. It would probaly be best to go for something in equal parts like 20-20-20 with trace elements Boron,Copper,Iron,Manganese,Molybdem,Zinc.

go to your local garden store and find some soil and ph test kits, they come in handy for deciding what to add
