They all look cloudy/opaque to me so really any time you're ready. I use to wait for a little amber but the trichs are starting to breakdown at this point so honestly, once they change from clear to 100% opaque you can safely harvest away.
Cut the plant off at soil (coco) level, hang upside-down in a dark cool place and allow it to dry until you can snap a branch, usually a week to 10 days. A grow tent with a 65-75F with a 55% humidity works great. You never want the flowers to dry out completely. Then remove leaves, clip flowers off and store in a jar or bag which will need to be opened (burped is the common term) daily to remove any built up mosture. Leave the containers open for 5 minutes to a couple hours depending on the moisture level. This is where experience comes into play, learning when to jar the plants and how to burp the jars and getting a good cure instead of totally dried out buds or worse, mold/bud rot. It'll take a few trys to learn it but once learned it becomes much easier. If you jar too soon you'll get a lot of moisture build-up which can easily lead to rot and mold. I've taken them out of their jars or bags and put them in a paper bag for a few hours to a day or two and then put them back in their jar(s).
Getting this one right will give you exceptional smoke. Getting it way wrong could wipe out your entire grow. Isn't this growing thing fun
You've been doing great so no reason to think this will be too difficult for you
but the fact you explained the drying and curing has made my day because that would of been my next question haha
