I can say for certain that your buds were not decarbed, so that's probably the biggest issue. Next time you should decarb at 240ºF for 60 minutes. There was very little THC in the buds that went into your butter. Almost all of it was THCa, which won't get you high. Decarboxylation changes THCa (which is what the plant grows) into THC, which is what creates the euphoric effects of cannabis.
The next factor is how much butter is in each dose of the edible you made.
