lets say if i have a Librarian and he arrives via DeepStrike would he be able to use a blessing psychic power?

No, the reserves rules forbid it.

Ok i see now, thank you

Well. It depends on the Blessing. If the Blessing is to be cast at the start of your turn, then no. If it's cast at the start of your movement phase or later, then yes, since the limitation as stated on page 125 of the BRB explicitly says "...that must be used at the start of the turn..."

Blessings must be case at the start of the turn.

I stand corrected, I didn't recall that entry. I was thinking from the perspective of Psychic Powers that are Blessings in nature cast in your opponent's phases (e.g. The Shrouding for GK, or was it Sanctuary?)

Also, keep in mind the timing of events:
The very first phase is the movement phase, so therefore your start of turn will also be the start of the movement phase.

This has been answered in a FAQ that I do not want to bring up here, because I see it every week when this question is answered. It is also poorly worded, leaving some to believe that blessing get a free pass and are not bound by page 125. I simply do not want to open that can of worms yet again to explain that the FAQ does not say anything of the likes.

Those powers aren't "Blessings" by the rules, though. They function similarly in that they improve a unit's capabilities, but they do not fall under the psychic power category of Blessings found on p68.

Yeah. I got confused by myself.
