It's still pretty hard to tell - but to ME it looks like they're becoming all cloudy... Now it's going to depend on what it is you want from your weed. If you only want a head-high, harvest when all the trichs are cloudy... if you want a combination of head-high with a good body relaxation, wait until you can see about 10-20% amber... if you wait longer than that, you'll be stuck on your couch - but some people want that! I'd still tell you to get a jewelers loupe - they're pretty inexpensive... Go ahead and feed her .... you probably have at least another week...
Cheers!
