The Greens picked up their first point since late November with a thrilling 3-3 draw at local rivals Wingate & Finchley a couple of weeks ago.
After falling behind, Niko Muir's penalty levelled things up before the break. Billie Busari scored a superb solo effort to make it 2-1 before two quickfire goals gave Wingate the advantage.
Two ex Greens, Ogo Obi and Andronicus Georgiou, netted to give what looked like three points to the Blues, for their own first win since late November. However, debutant Leo Sery rose highest to nod home a corner to salvage a point and put an end to the Greens' run of defeats.
