To begin with the amount of material you used even with a high yielding tree won't yield much. Twig and phyllode should be fine but you didn't use anywhere near enough.. remember 35g of twigs contains the wood as well.. so that takes even more off the amount you were using when you remember only some of that is twig bark. I'd start with like 150-200g.
It looks a lot like retinodes, but as I said I find the differences between it and provincialis very difficult to tell.
Could you share your extraction method in writing? That video is half an hr long.. but from what I saw that person is doing an STB tek which isn't generally found to work well with acacia. A/B recommended.
Also don't expect to get crystals all the time either.. Acacia often contains other alkaloids and can come out as more of an oil
the 'nen method' should work fine:
