Phalaenopsis white dots on the leaves.
 

Hello I have problem with my phals, I do not know what can hurt them, maybe spider mite? I'v seen them on dendrobium but on phal not. I do not know what to do.
I used spray by fungus and spider mite.

Please help me and my phals.

I hope someone can help, that looks terrible :(
Did it happen all at once or over time? Best of luck to you and your plant

It will probably happen in about a week, I hope they will live :/

- Does the white can be scratched? I don't think so but you never know… If you use a magnifier, is there some sucking point?

- Is it smelly? Looks like liquid inside? (do NOT cut to see) = somehow a bacteria is eating up inside.

- Wipe a bit of cotton wool with alcohol on (title 70°, if you don't have, take methylated spirits, add about 46% of water to it and up you go). Wipe under the leaves especially start with the nice leaves, end with the ugly ones. If there's yellow-brown mark on the wool, there's spider-mites. Anyway, given the state of the leaf between the "dots", I guess there's been quite some around.

- Has the phal been subjected to temperatures below 18 with wet roots? So it could be edema (nothing to do save watch out nothing else bad happens)

Can we have a general view of the plant?

Now for cures:
- I'd treat for spider-mites, the plant and all the others around. (emulsified neem oil, Masai™, pyrethrin based products labelled for spider-mites)
- If it smell bad, something is rotting, there's be some cuts (or none if no hope)

That's all I can tell for now. :-/

I keep my orchids in small greenhouse (2x2x2meters).
Temperature: 15'C at night 30'C at day, at day work 2 fans and 40-60% humidity. It certainly does not sunburn, I always water the orchids in the morning with rainwater. Bumps are hard and do not smell, I don't see sucking point.
Yesterday I sprayed all on spider mites. In greenhouse I have many different species but sick just some phals, not all, some have a few other many dots.
