dj, you need to stir and keep on going.
After your step six,
7. Stir, the given stir stick work great but I hear the ends are bigger than before.
8. Draw as normal
9. hold for desired length
10. Draw as normal
11. Hold for desired length
Rinse and repeat until you get no more vapor after stirring.
Eventually you will get nothing or near nothing after stirring. Then you can take the fat end of your stir stick and crush the contents in the wand and stir again. You will get probably one big hitter, bigger than you may expect and then maybe one small one but then it is pretty much done. Skip the crush step if you want to save some strength in the abv.
Also, you turn the wand in the vape to expose more herb to vaping. Generally if I do this its the second or third draw before stirring.
Keep in mind, using a grinder will give you a bit more thicker draw but if you cut the weed up instead of using grinder you will likely get more draws but slightly less thick. I recommend a grinder with a kief catcher and then you can use your wand hash and kief off and on, wand hash can be used the same a kief if scraped out. Wand hash is basically condensed THC. Highly prized stuff.
Soon enough you will know by experience when to stir and whatnot. Until then keep an eye on your ABV, it should be a golden brownish color. It will vary on many factors, what temp you vaped at, how far you vaped it, the type and quality of the material used just to figure a things but it should not be black and without green specks. Da Buddha vapes evenly due to good air flow through the wand so as long as you stir, it should be fine.
Also understand, though slightly rare but I have seen a few times and is reported more than few times as well. Some genetics or types of weed simply do not vape as well as others. I have never had the opportunity to be in a position to know exactly what I am using so I cant say which specific strains or plants that tend to have lower performance with vaping.
Since you do not mention stirring, I think that is your issue.
Happy Vaping!
