Indica Flowering for 12 Weeks?

My plants are about ready to start their 13th week flowering. They've been really healthy the whole flowering phase. I've been monitoring the trichome coloration and most are cloudy white with about 1 out of every 75 or so amber colored. Still some white hairs but I'm thinking they might be new. It's a "mostly" indica strain so I was expecting a larger ration of amber to white trichomes a couple weeks ago... certainly by now. Have I waited too long and missed the peak harvesting time? Any advice would be greatly appreciated. Thanks all...

i'd prolly chop soon

They look so dense and big, good job they look good, and delicious

Definitely good sized buds and super dense. The strain is chocolate chunk. I guess I'll start flushing and get ready for the harvest.
