We need more info like where you are located, what soil this in planted in, what fertilizer you have been using.  From the looks of it, the palm is hot and underwatered but just a guess

Located in the Balkans, North Macedonia. Palm is watered regularly 2-3 times a week. There was a lot of hot days in July, like 40+ celsius for weeks. Maybe it is overwatered or something, but i dig a hole next to it and the soil looked ok, not too much moisture. Unfortunately I was never used any fertilizer so far.  Is it ok to add fertilizer now? I am looking for 15-5-15 but someone recommended 20-20-20.

Someone familiar with your location needs to comment.  I am not familiar with climate in that area.

You should use the first fertilizer mentioned, as palms prefer a 3-1-3 ratio for the macronutrients,  NPK.

Thanks!

Is it ok to add fertilizer now? Because the palm is obviously under stress. I am really in status quo and don't know if it is under or overwatered. The tree was much happier before.

Wow it went downhill a lot.  Is the first picture when 1st planted? 

I am not sure of the cause on yours but you can't overwater mine in summer.  Mine get 2 hours on drip every other day and are growing like weeds.   

When yours was  first planted if the palm looked healthy it could have declined from then because of being dug up and transplanted.    Do you have other healthy Windmill (Trachycarpus fortunei) palms in your area?

2 hours of drip every other day??? I am watering like 5 mins max with slow water 2-3 times a week. Yes there are healthy Windmill nearby, the most critical part here is winter, sometimes temperature can go below -15 celsius. It was November when we transplanted.

How much water is actually being applied in your 5 minute application?

Not sure but around 10-15 liters maybe. But the terrain is little bit tilted and the water is not sitting at the tree. 

[aztropic]

If the applied water is running away from the tree because of the terrain,then the tree is not really getting watered... The water needs to be applied slower,or maybe build up a ring around the tree that will hold the applied water in place. Those Browning fronds on your tree are due to heat and lack of water.

A ring with 5-1 gallon drippers per hour = 10 gallons every other day

Lay off the fertilizers.

Check the pH of the soil.

Unfortunately I am not able to find any 15-5-15 (3:1:3) ratio fertilizer so far. Only 15-5-30 which is used for Banana. Can I use 15-5-30 or too much Potassium is bad for the tree?

Thanks, I've just ordered soil ph tester.

Trachycarpus fortunei (Windmill palm) are not the type of palm that can tolerate that kind of heat for extended periods. It would even be less equipped / adaptable after a recent planting. Was it field dug / root pruned or a container / crate palm?

Yeah looks like heat cause this problem, coz only the top leaves was affected, lower ones are not brown because of the shadow from the top one probably. It is around 8 years old and fully grown in field 150km south from my location, at the border with Greece.  (It is even hotter there).

 Also all leaf segments are folded and staying that way,  maybe it is some sort of mechanism to protect against direct sun.
