Hey man!
Take a bud off I reckon that's the best way to see! And yes a microscope could help, although I hate using them myself lol
Auto breeders seem to have a tendency to understate the length of thr growth I think... So I wouldn't be surprised if they were to take a bit longer...(talking about mine...yours actually look riper than mine lol)
Here are some pics:
#1 (started the flush a few days ago! hope it's not too early...)
#2
That's the one with the Haze smell!!
I want to keep this one 2 weeks longer or so
Peace!
