Hot Thai chili peppers diagnosis

[volbox]

Hello guys,
I've started growing peppers this year and I decided to plant hot thai peppers. They were growing fine until lately ... Some black dots appeared on the leaves and I cannot understand what it is.These black dots are then becoming holes. If you could help me finding what it is it could be great    As you can see on the pictures ( even if they're not that clear) the new leaves are curling up and drying on the edges , I thought about a calcium deficiency but I'm not sure.

There could be many factors with what is going on in your situation. If I were you I would consult this website.

I would if they are becoming dots then it could be sun damage. 
Is your plant used to this sun like trained to it, or did it come from indoor?

Thanks for your answer. It is sun trained.The plant is still growing at the moment but these black dots are still there even on the new leaves. If you want I can take more pictures tomorrow.

Hello, here are the pictures. I don't know if they're clear enough but I lose some quality when I upload them. As you can see it on the 4th picture it starts on the edges.

Hmmm, How is the soil, does it hold enough nutrients? 
If its not nutrients deficienty I would say its an infection. If it becomes extremely severe cut away the leaves of the plant except for the healthy leaves. Try to keep a keen eye on your pepper plant. Most plant recover from a small infection. The only problem is a small timeloss in growth.

Thanks for you answer but I think the infection is as bit too severe since even the new leaves are getting this black dots

According to this website : https://www.gardeningknowhow.com/edible/vegetables/pepper/common-pepper-plant-problems.htm 
 
This is their tip:
Growing disease-resistant pepper varieties, rotating crops, and keeping the area free of debris will help minimize pepper plant problems. Excessive moisture is responsible for most pepper plant bugs and diseases. Good drainage, adequate spacing, and proper watering should help alleviate these issues.
