2 weeks 'till harvesting

Anyone can help me on it?
I am ready to harvest in couple of weeks and have a general question. when i will be looking at the trichs, should I start on the main cola or the bottom of the plant with the popcorn buds.? which r gonna be ready first?You guys think
If so i want to cut the ripen buds first and let the rest to ripe more. Thanks

3 plants have been under 400 hps about 10" above the plants and the plants r 2.5 feet long

well, mine always finish up top first on the colas. Then the lowers a little later.

Yeah I think you might find mixed answers on this, since some of my lower buds are finishing faster on my plants...so not sure if it is universal to all plants.
