How to bleed the zones on this?

Thinking of starting where my finger is... not exactly sure which Iines to just off with such a complex setup. Looking to bleed the zones valves because the baseboard heat just isn't getting super hot.

    Looks like you need to bleed though the return .. The feed in is though the supply so need to isolate the return and manual open the zone you want to bleed though the return. Hard to tell with the photos which valve need to be closed....

    The zones that don't seem to be getting hot ,are they toward the left ?
    I have enough experience to know , that I dont know it all
