A lot of them do have a bit of a rest period during winter. You might see some new growths starting soon on the milts and once they are nearly mature, they would put out spikes. The days are getting longer so that should tell them it is spring.

Milts tend to grow top growth in spring and summer. They don't do much in winter. They should do ok in Phal light, but like it cooler. Down into the 50s in fall and winter (at night, warmer in day ) They will usually spike in fall as it gets cooler at night.

There could be many reasons for the stalled out situation. Stress can cause orchids to slow down and/or stall. Growing conditions that are less than ideal can cause orchids to sort of shut down and go to sleep.
The one thing that pops out to me is your low temps. 50 degrees is too cool for the majority of phals. Especially too cool for the complex hybrids. Some milts might be Ok w/the cooler end of that but even many of them are going to be happier if not exposed to temps that low. I don't know for sure that this is the problem...just pointing out it might be contributing to the issue. I can tell you from personal experience...my winter temps drop to 58-60 and I notice a slow down of growth in the winter on all of my phals. I would be concerned about extended periods at 50.
Also, you mention bright light but what is bright to your eyes might not be bright enough for the plants. Any plant can survive under insufficient light but they can kind of snooze for what seems like a long time before they actually go into decline. What direction is your window facing and are there any obstructions (roof eaves, trees, etc)?
Too cool temps and insufficient light would be what I would look at first.
EDIT - just so I'm not confusing anyone. Most milts don't like really warm day time temps but that doesn't mean they want it really cool at night. It's really more about controlling those day time temps. Not all, of course, but many.

I agree 50F is pretty cool. I thought you just did that with the Phals for a couple weeks to induce spiking which is all they need. They may not even want to spike in that cool of temps for prolonged periods. Mine always start the spikes after being removed from cooler temps and brought back in to normal room temps.
The Milts, I also agree with Katrina. For sure they get stressed when over heated. But they are not cold growing plants. They are just not heat loving plants which is different.
In those ongoing cool night lows, that non draining glass pot is also not a good conditions. Cold and wet cause fungal and bacterial problems.

Orchid Picture
Attached is a picture of my "dormant" orchid plant.
I bought this more than a year ago. Looks the same as the day I bought it.
The clear glass enables me to monitor moisture. Plenty of air gets in and around the bark.

The picture is pretty tiny, but isn't that a new growth at the base?

Here are several links to Miltoniopsis care. Note they need good air and do not like soggy conditions, which cause rot where no oxygen can get in. I still have concern for that one in the glass pot. You need bottom holes and even side holes are great in addition to the bottom ones. Some people on here do use glass bowls but they drill holes in them. Or clear plastic pots allow some root monitoring also.

Air doesn't travel through the glass...so, it's not getting the air exchange it would in a more open and/or porous container. Keep in mind...these plants grow on trees (most anyway, for sure the ones you're growing) and in nature their roots are typically very exposed to breezes. Using clear plastic pots w/holes or slits would be better than the solid glass w/your bark medium and it would still give you the ability to see the roots. I've seen people use glass containers w/success but those are typically done w/little to no medium so the air does travel down into the container and around the roots.
The plant itself doesn't look bad but the "pot" might be a bit too big. Maybe. You still haven't mentioned what direction your windows are facing and whether or not there are any obstructions at those windows so I'll go back to light and temps being those elements most likely in need of some tweaking. And, if it were me, I would definitely consider a different pot/container in order to have the best success for the plant(s) to thrive moving forward.

I have noticed a bit of a difference in my plants since raising the night time temps from 55 to 60 and my daytime temps from65 to 70. I just have some concerns about my Cymbidium ( which will go outside once frost is over ) and I don't know yet how it will affect my nobiles and Miltoniopsis. I read on a lot of sites of pro growers that they keep their greenhouse temps at 55, but I am learning that it seems to be too cool, at least for me.

There is a huge difference between a basement with nights of 55 F / 13C and days of 66 F / 19C, compared with a greenhouse with nights of 55F and days of 80 F / 27C. Most warm-growing plants tolerate cooler nights much better if the following day is nice and warm.

I'll try and post another picture that's bigger. The picture I took is large, but it scaled down on upload.
