I have some Zkittlez OG auto from Barney's that are at 84 days and I'm pushing them another week at least. You can definitely add some weight on in the last week or two.

Keep in mind the breeders recommended flowering time is an average from their grow environment to give the growers a rough estimate so they can adjust accordingly. You will want your trichomes to be 50% milky to 50% amber once you have a close up look.

@Johnd1995 Hi mate your doing really well however if you really want the couch lock experience I would leave her for another week to 10 days atleast. When you get your new microscope do a trichome check straightaway and keep monitoring until about 40-50% of the triches are amber. This will give you the result you are after. You just gotta love Barneys farm their weed is dope 😆

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
