Its not uncommon for the upper colas to mature faster. I often harvest upper parts of the plant and allow the lowers to mature an extra week. Ive also seen a lot of autos go way beyond their suggested finishing times.
I had the same thing on my first grow and I just cut the tops and let the rest go another week or two. It’s not bad either because it splits up the trimming
I've used the percentage of amber trichomes as a guide for nearly 15 years. I count 20 trichomes on a few different spots on the flowers themselves (not the sugar leaves) to get an average. I've chopped any new strain I flower out at 5, 10 and 15 percent amber trichomes to find the peak point of ripeness. Your growing environment can slow down or speed up the maturation rate, so breeder's "Flowering Times" are only a suggestion on when to begin watching how mature your plants are.
