Color change

[joeybear]

I filled my Protank II with a nice, light colored juice this morning and after vaping all day, what's left is a murky brown color. The flavor is still decent. Is this normal? Seems odd that it became brown.

It's normal. It's "caramelization" of the juice where the wick meets the coil. If you keep topping that tank off (like I do) it will get darker and darker and probably thicker also. I like the darker taste and just thin it out with a few drops of distilled water when it gets too thick to help it wick better.
