Do you guys log spices?

Nah. Only if I'm creating a recipe.

^^ this^^

for tacos and taco like products

I use

1.5 ounce of chili moledo (mild)
1 tsp of chipotle chili powder
a handful of cilantro chopped (or a tbls or two dried)
1 or two tbls garlic powder (straight no salt)
1 tsp sugar
1 tsp oregano

1 or a few hot peppers depending on what kind they are and how hot. 1 habernero or 1 or two jalepenos ect
1 or two onions

and then the meat. (I use turkey breast either shredded adovada style or ground taco style.

I do for two reasons.
A) It helps me remember what I used if I want to make that recipe again.
I log EVERYTHING that I put in my mouth. I found that if I do this, I won't cheat by "forgetting" to log that one teeny little cookie that I steal off my husband or whatever.

If I'm logging a recipe I add them so the recipe is accurate. If I just toss something together I may not think about it though. I probably should. I use a lot of cumin.

I don't. They only get used when I eat dinner. My parents usually cooks dinner and I don't feel like bothering them every time asking them what spices they used
