Had a little heat issue on one side of my room and these are the results. Can it be fixed?

It has been determined by some of you fine folk that I had a heat problem this round on one side of my grow room...One side is frosty one side...well...not so frosty... can I fix this or is it too late? I plan to harvest in about two weeks.

only shot I got with hardly no HPS... its a couple weeks old
