BioBudsanswered grow question 3 years ago Humidity could be your answer here, the other is budhealth. Yours still look crispy green, so either you are feeding too much for the flowerings stage shes in, which keeps the buds healthy, also the high moisture in the air keep them moisturized too why you see that maturation is slower. So if you arent fushing, start. Just ph water. If you are flushing give less. Just let the medium dry up a bit. Let the plant eat its own nutes, so the resin production kicks in and they will enter final stage.
They look great just be patient it might take longer.
