Rate my Itinerary: Ladakh (and a bit of Himachal Pradesh)

Hey!

So I am currently planning my trip to India, more specifically Ladakh. I will fly on the 12th of August, and plan to stay for roughly a month. My plan is to move upwards from Delhi to Ladakh, spending most of my time there. Here's my rough outline:

13.08: arrival in Delhi, getting settled
14.08: train to Shimla via Kalka
15.08: exploring Shimla
16.08: Kullu valley
17.08: Kullu valley
18.08: Manali (some small treks, outdoor activities)
19.08: Manali
20.08: Manali
21.08: Manali
22.08: Bus to Leh
23.08: Bus to Leh
24.08: relaxation day
25.08: exploring Leh
26.08: daytrip around Leh
27.08: Markha valley
28.08: Markha valley
29.08: Markha valley
30.08: Markha valley
31.08: Markha valley
01.09: relaxation day in Leh
02.09: Nubra valley and Pangong Tso
03.09: Nubra valley and Pangong Tso
04.09: Nubra valley and Pangong Tso
05.09: Nubra valley and Pangong Tso
06-11.09: unsure yet
12.09: flight back from Delhi

At the end I left open some days, that I'd either spend more in Ladakh, maybe going to things like Tso Moriri or some Gompas, or rather return earlier to Delhi, spend some more time there and maybe visit the Taj Mahal. I guess a few days of puffer are always good, for food poisoning or other things.

So what are your opinions? I'd like to move northwards and fly back to Delhi, but I am worried that due to the monsoon it may be smarter to first fly to Ladakh and return south by public transport, since the weather in Himachal Pradesh is supposed to be better in September. I don't know if the moving up by bus will help with acclimatization, since Manali itself is not too high.

From what I read online it should not be too hard to find people to join me on treks in places like Leh or Manali. Would you agree with that? Furthermore, what is the general touristic crowd like in these places? Myself, I am 26 years old, male from western europe. Will I stand out among other tourists? I am aware that I will absolutely stand out in India, but I mean more whether there are more people like me (age-wise I guess) traveling alone there.
