My first grow and 2 different problems!!!

Started my first grow in a small wardrobe using some flourescents just as a test. It was growing pretty well and not long ago I found out she was female but about 2 weeks into flowering some of the lower leaves are starting to go yellow and brown and seems to be slowy working its way up, also a few of the leaves around the flowers are turning a really light green/silvery colour. i have added fertiliser with a ratio of 10:10:20 but the problem is still there. Any help would be much appreciated.

Cheers
