Add a couple more weeks ... needs to swell and have pistils mature ( calyx ) .... This where bud will show true ripeness - not on leaf .
Note that not all strains amber off like you might think.
Some will “ amber “ AFTER chop as plant dies off.
Some plants get harvested with some white pistils - but you want at LEAST 75-80% of pistils to color and pull back . This another sign of ripening and last stages. Fade of leaf can happen as plant finishes , she may stop drinking , or sugar leaf dies off. There are other signs that show maturity.
The nanners are what they are ... some plants rodelize ( stress / environment / feed ) and do a “ self preservation “ move for survival. Run them as long as they need.
