Yup, too much oxidiser in the fuel mix as shown by the green flame. Possibly due to copper pipework being consumed as the system does not use TEB as an ignition source. (TEB was used in the SR-71 which gave a lovely green flash at engine start).
A tremendous effort, a perfect launch, precise manoeuvring, recovery to the vertical, a pinpoint landing ...........but just a bit fast due to low fuel pressure.
