i bet the white pistils are new growth?
I'd focus on the trichomes of calyxes of non-new growth.. unless you want to wait for that new wave to ripen.. then you'll have some portions being extra ripe and others being less ripe in a more extreme way -- always happens, but this would exacerbate it further.
Trichomes, bud density and pistils coloration. Use all three. If new, experiement with different points of harvest window... 10% - 100% amber? i like it closer to 10% but you may not. Assessing trichomes isn't as neat and clean as it sounds. you'll see different ripeness at different levels of the plant. Apical dominance will cause stuff higher on the plant to ripen faster.
