Almost harvest time? Yellowing (pics)

My plant is about 7ft tall, and its fully into flowering. All the leaves are starting to turn yellow. I know this is a part of flowering, but it seems to be yellowing rather fast. THere are still some nutes in the soil, i want to flush it soon and harvest around monday or tuesday of next week. Here are the pictures, let me know if you think theres anything wrong. Thanks!
also do you think its a good time to harvest?

You can def flush now. Can't see the buds that good but anywhere from 1-2 weeks seems like it would be fine

Yellowing of leaves is normal. It's caused by the low nitrogen used during flowering. Let's see some pics of the final product later, okay?

Since its already yellowing prior to flushing 1 week of flushing will be sufficient. Make sure your final flush is a few hours prior to sun set this will get most of the nuts out of the soil, then allow more nuts to drain to the roots during the night. Make sure you harvest prior to sun rise to prevent the nuts being brought back up the plant.

Sweet purple strain. Do you have a handheld micoscope to examine the trichromes? That is the most precise way to determine the harvest window.

No i don't have the micoscope but i might be able to get my hands on one. I'm letting the rain start to flush it on friday and then monday morning then harvest monday night.
thanks for all the help, i'll post pics on this thread when its all chopped and i have a high quality camra.
thanks!

Harvest them as close to the morning prior to the sun rising so as much of the plants starches, and sugars are stored in its root system. The rain has been brutal up here in CT, perfect for outdoor growers for flushing though. I hold no branches broke from getting to heavy due to the rain.

No rain has treated me great and i didn't top it to much so nothing major broke off. havesting this weekend, its dropping to 36 and i don'[t wana risk the frost
