You'll have to pull the weeds out by hand, loosening the roots with a small hand fork or trowel ... any weedkiller will kill the hedge too.
As for feeding - I use Fish, Blood & Bone which is a slow release organic fertiliser - available from most garden centres, DIY places etc either in powder or pellet form - follow the pack instructions for amounts etc. I use it twice a year, once in the spring and again in mid summer.
If the twigs are dry and brittle and have no leaves anywhere on them, snip them out with a pair of secateurs. Getting rid of them will allow more air circulation which will improve the health of your hedge.
Reducing the height of the hedge by half at this time of year will ensure good fast growth and a handsome hedge
