    Some good news and bad news for
    you....

    That belt deflection is perfectly normal.

    So, good news: Timing belt tension is not your problem.

    Now, bad news: Timing belt tension is not your problem.

    Keep looking.

    Have you verified, cam position with crank TDC? Check your belt tension on the passenger bank down to the crank... see if that has excess slack on it there.
