So, I've had this little guy for 2˝ years now, and finally I decided to ask what on earth could be going on with it.
As soon as I got it home, it started getting chlorotic leaves like this:
My theories have ranged from, virus, nutrient deficiency, light issue, to variegation.
It has been growing right next to my other Paphs from the Paphiopedilum subgenus, getting the same treatment, culture, fertilizer, you name it, and none of the other have ever shown any signs of similar issues.
There's no pitting, no cell collapse, no deformations etc; just the lack of green colour. The leaves also green up after a while, which is why the older ones are greener, but they never go fully green.
It's a good grower and seems healthy and happy if it wasn't for the strange looking foliage...
EDIT 1:
I need to stop editing the post.
I posted this on Slippertalk as well, but thought it's always better to get more eyes looking at it. The only comment I've gotten there so far, says virus, so in wild panic, I threw myself out onto the web to check pictures of virused orchids. I can't find anything looking remotely like this, so I'm even more confused and concerned now...
EDIT 2:
Added some more pictures, The fourth picture is from when I got it home (it's still in the same pot, so it has grown quite a bit), the fifth picture is another villosum I had (bought it as a henryanum, though) for about a year, together with my helenae, which I had for about 2˝ years before killing it.
The reason why I'm posting the last picture, is because these two stood at the same place as my weird villosum. They got exactly the same treatment, culture, everything, but none of them looked like this. So I don't think it's cultural.
