1kg MHRB extraction low yield. Help!

[Smoknhorns1]

I got a kg of high quality Mhrb and I have only yielded about 4-5 gs of finished spice. I have done this extraction numerous times before but this time I’m not getting anywhere close to my usual or avg end result. Any suggestions as to why this is happening?? Many thanks and I appreciate your help friends!

Back in the day I did 100g MHRB extraction and got a lot of g. Now, a few years later, I used one of the teks on this forum. It was quite similar in nature. I used 50g and got 0.070mg.
