She will probably swell a little more but looks like she is getting pretty close. They only way to be sure is to check her out when you get your microscope. If you are looking for couchlock then you want mostly cloudy and some amber so I would start flushing as soon as the first Amber's start to appear and she should be pretty stoney 2 weeks later when you harvest. It is really something you have to play around with to find out what you like. You can always harvest a couple early buds to have something to compare the different effect at different stages of ripeness. Good luck
