Leathery leaves turning yellow with several new spikes

[pgonzalezz]

I'm confused, I know orchids are delicate and need a lot of attention but although I thought I was doing everything the way is suppose to my orchid's leaves are turning yellow and leathery. However I pulled it out and noticed that there are several new spikes growing and the roots seem to be okay. Any suggestions as to what I am doing wrong? I water them once a week, they are in my kitchen facing the window (West). Thank you!!!
