My plants are dying HELP!

My plants are dying HELP!

My plants have been dying. I think i might be over watering but I'm not sure. I have a blueberry plant,strawberry, calla lily, chocolate cosmo, catnip and chocolate mint, lavender, mini roses, tomato and 3 fuchsia plants. all of my plants except the fuchsias are dying. they are turning yellow then becoming brittle. i water everything daily right after i get home from work. and fertilize every two weeks. I try to keep the fuchsias in the shade. everything else is in full sun, oh and all my plants are in pots on the balcony. all the pots have drainage holes. any suggestions are appreciated. oh i live in Portland OR i think that's zone 8 if that makes any difference. Thanks
