I've had a rough first tent grow and at week 4-5 of flower I'm getting close to 50:50 ratio of white to brown pistils. My last grow was a few years back and I remember looking under a loupe or microscope for creamy white mushroom caps (forget the proper name), but I forget what part of the flower to look at....it's a piece of frosty flower leaf right? Thanks!

you should really post a picture of your plant so we can see. Its possible to scope to early and it will for sure trick you . If you cant do a pic wait to all the hairs changed colors before you scope .
