Is this ready to flush ?

what week are you in from germination? The breeder info says 9-10 weeks from germination. If you are in week 7-8 I would start to flush. Make sure the plants do not get any water 3 days before your chop. Also a hand held microscope would do you good. You can see various macro shops and use them as guidelines for when to harvest. But for now check your breeder info.

I would do some research on flushing. I used to flush for 26+ years... Last 4 years I stopped and have better tasting flowers. https://www.rxgreentechnologies.com/rxgt_trials/flushing-trial/ Look up more if possible.
