I need a diagnosis for a phalaenopsis plz

[Klingfilm]

Hi everyone,
I am a brand new orchids learner. I've started to buy some phalaenopsis and sometimes unwanted events happen.
I had a nice one with big flowers and within a week something weird happened...The spike color changed to dark brown and the flowers fell down quickly. But, I discovered that I could "skinned" the spike just by touching it between two fingers. I was able to peel it off with a viscous feeling revealing the core of the spike.
I decided to cut the spike right a the bottom.
Also, I noticed a brown spot on one leaf that I can't explain too.(pic A)
A lot of root tips are brown or black, even the new ones.(pic B)
And finally, I see on a nice green and crispy leaf, a strange spot, which feels like irregular vesicles. And if I let the light goes through the leaf I see a clearer spot at the same place. (Pics C-D)
Could you tell me if all this is normal?

First, welcome to the site. Unfortunately, you can't post pictures until you've made 5 posts.

It sounds like you've got a case of brown spot or some sort of rot going...I'll wait until I can see the pictures until I attempt to go further.

It looks like something fungal. Is the spotting progressing quickly or slowly?

[Undergrounder]

I think it's just insect damage, it looks like something might have been eating at the undersides of the leaves.. new plants often come with some critters attached.

The plant actually looks pretty healthy, the root system looks old and neglected but it should last until you can grow new roots... make sure it's in a good, free-draining medium, give it plenty of water and don't forget to give it lots of light.. not harsh hot sunlight, but most people under-estimate how much light they give their Phals and they need more.

I concur with Undergrounder, it looks like insect damage on the leaves. Small sap sucking insects can do quite a bit of damage and since Phal leaves stay around for years they will constantly remind you that they existed.

Try a solution of a few drops of dish soap, and equal amount of cooking oil, and about a quart/liter of water and wash the leaves to kill the pests. You can clean the leave regularly until the pest problem is resolved and continued use will prevent most problems from beginning. Most dish soaps will also act as a control for fungus as well.

The roots look ok but dry. The black tips on the roots are normal but not actively growing roots, when the roots are healthy and actively growing the tips would larger and greenish black.

Good culture goes al long way to protecting plants from disease. Here's a link to an article that really does a great job discussing Phal growing

I forgot to tell you that the leaf on the last picture is not the same as the one on the second picture. The brown spot is not on the leaf which has the "bubble" texture.

My plants are being kept inside my appartment just by the window. It's winter time and the temperature is about 22°C inside. But, the temperature is a little bit cooler by the windows. The sun is up about 8 hours a day.

the last pic looks kind of like sunburn, but can't be too sure because the picture is kind of blurry. What way does the window face that you keep you Phal in?

[Klingfilm]

My window is facing N-O and in winter time here in Quebec there is no way my plant can get a sunburn. I looked at my plant carefully and I couldn't see any insects anywhere.

I want to say that the clear green spots on the first picture attached cannot be seen if you don't let a direct light source going through and the texture from the top of the leaf is not damaged. It seems to be inside the leaf. What is this?

Hello fellow Quebec citizen ^^. The brown spot looks like some rotting I had on the leaf of one of my phals. Is is mushy? If if is, it's probably a kind of rot. I'll leave the rest to the more experienced members. :P

Good luck and Welcome, we're glad to have you

Hello and welcome. I defer to the other guys re: bugs. I'm by no means an expert. I would have guessed too that the brown spot is sunburn. If it is hard and not growing I'd just keep an eye on it. If anything is mushy, cut off past the mush and dust the cut with powdered cinnamon. (all this learned here)

[Klingfilm]

The brown spot on the leaf was mushy and became dark brown close to black. I decided to remove it. It was not a sunburn I guess because the weather is cold outside here and cloudy too.
If I have bugs, am I supposed to be able to see them ? I don't see anything with my eyes?
