Some questions on trichs before harvest.

My first grow, is getting close to harvest, by looking back at pictures etc, I am figuring she(is one plant) has 8-10 days left. I have a few questions.

1) I see some amber, only a few on each leaf, but all are cloudy, is it time to flush now or wait until 40% or close turn?

2)If I am using the leaves for hash, should I flush for less days so the leaves don't dry up?

3)I have heard the last week the buds can get much bigger, is that true, or just normal growth like the past few weeks.

I added a few pictures below from a few days ago, thanks for answers and + rep to those who give me good advice!

first of all nice plants. i would wait till 50-60% amber but it is kinda a personal preference. the more amber the more couch lock the stone . ive harvested a sativa with all clear thrichs and the high was like doing whippits. those plants look so good i dont think its ganna matter. enjoy..

dude follow this chart and you will fantastic everytime in pulling down. good luck to you

sorry i missed your other qs: always flush around 1-2 weeks(minimum) before you harvest to give the weed a chance to push out all those extra salts and nutrients so your weed tastes oh so yummy. lots of water. at least double your pot size (in gallons) worth of water per flush. when making hash it doesnt really matter if your leaves are dry or wet....put the leaves in a freezer (ziplocked) or a brown bag....then whatever method you use to make your hash the crystals will break off easier from the lead..........thus leaving you with danker hash

thanks, I did do a test smoke about a weke ago and was a strong head high, really good taste like fruit loops lol
Is a blueberry/g13 stain from bag seed(blue goo).
I am hoping for 3 to 4 oz from this one plant dried, I broke off the top so now I don't have a main cola, but 8+ smaller ones.
I am growing in a 4 gallon bucket, DWC, with a bunch of airstones and pumps. Using GH micro and bloom(lucas method), botanicare sweet and started humbolt gravity a week ago. I just bought some GH floraclean to flush and have been using cannazyme to prevent any root issues.
