I have had my orchid for about 2 1/2 years. It has bloomed three times with about 10 blooms on both stems. I water it once a week, soaking the plant in the pot for 5 minutes. I fertilize twice a month. Recently the leaves have all gone limp. It gets plenty of light. The orchid pot is in a pot which sits in a saucer of water/pebbles. I mist almost daily. Thanks you!!
My first suspected cause will be just a little too strong of a nutrient mix. This can build up as salt over time in your container. This can happen with pH issues, which can be attributed to a different ratio of nutrients than required by the orchid, as well.
Be sure that this is an orchid fertilizer,specifically, and even better would be to use it as a foliar spray at half strength, but twice as often, instead of a root drench if that is the way this plant is fed.
I could recommend misting daily, as well. This can happen when the humidity isn't quite high enough. Even multiple mistings per day can help.

I have a beautiful display of orchids which have been given to me over the past four years. I’m no expert, but somehow I’ve managed to keep them blooming, they look magnificent. One orchid is a miniature. Would I be able to pot them altogether in a large pot, leaving them in the window where they seem to love it. They are taking over and the window is nearly obscured.
I think it would be very awkward. They like shallow plantings, and the large leaves would be going all directions. Plus the close proximity might set them up for fungal disease. If any are different they might need a different type of care. You could try keeping them in their grower's pots and setting them together inside a large planter. Just avoid too much crowding. Cover the top with dried Spanish moss.
Rainwater or tap water ?
Most experts are saying tap water is fine for orchids. If you see water deposits on your plant, you may want to switch from tap water to bottled water, but it's not necessary to gather rainwater. Here are some tips:

Is it a fungus or a bacteria? I hope you can help me.
If there is a sticky substance under the leaves check for aphids or scale insects. Here is more:
