I always leave mine in complete darkness for 2-5 days before chop.
Reason light degrades terpenes and cannabinoids.
those darkness days the plant is still growing/using water maturing cannabinoids and producing terpenes without the light degrading them. I've found I get tastier product using the dark cycle vs emergency lights on chop ..
Giver a try something To think about.
OP imo 1 plant looks slightly overdone heads are popped already , unless they are missing from you molesting it. 2nd plant needs about a week for couch lock harvest now for that up high
