When can i start flushing my plants. Its my first grow.

Hello.. Hope you are well.. 8wks is the usual time for most cannabis plants but sum can take longer.. For beginners its better to look at ur pistils-the little white hairs popping from her flowers.. Wen approx 2/3rds of these have turned brown she's ready to flush then harvest.. Another way ppl check is by getting a x60 magnify glass/loop and check the trichomes on her buds(trichomes are the little mushrooms that hold the resin that gets us high).. These start of clear then go cloudy then turn amber.. For maximum cannabiniod content u want to aim to harvest wen all trichomes are cloudy with maximum 10%amber..u will always get a few clear still but look at the majority.. Look up trichomes n u'll av better idea on nxt grow..she's looking nice and healthy tho so well done.. Stay safe n gud luck with your future gardens.. 👍🍀
