I wouldn't, but I'm not sure what the entire question is, so your way might work? I feel like consequences of the Potsdam Conference would be things like the division of Germany, the formation of the UN and Stalin setting up pro-Soviet governments in Eastern Europe.
The increased tension was not a direct consequence of the Potsdam conference, but more a result of the events in Eastern Europe and America making the Atomic Bomb. The Marshall Plan was also not a direct consequence of the Potsdam Conference but was a result of the Truman Doctrine. The British pulled out of the Greek civil war, the Truman Doctrine was issued. Truman believed that communism would appeal to people who did not own anything, so he sent General Marshall to check the economic situation in Europe. The Marshall Plan was formulated in April 1947 but only came into effect in March 1948 after the Czech coup. Therefore both increased tensions and the Marshall Plan are not direct consequences of the Potsdam Conference.
