the trichs were more than 50% amber
Yeah...on a leaf! you can tell by looking at the buds that they are not "ripe" but that is cool as long as you are not interested in couch lock...(I'm not) but you are!...but that is not my main reason for saying you were early...look at the full foliage and deep green...your fan leaves should be yellowing and even some leaf drop when the plant is ready to flower...it is getting ready to die when it is ready...a good flush will also help to lighten up the plant, or in other words...use up the N stored.
Trichs turn amber as they start to degrade, from time, temp, light etc. trichs on a leaf are the oldest, most exposed trichs and some will change color LONG before you are done...next round look at 5 weeks and I bet you have 5-10% amber on LEAVES.
This is just my opinion...good job dude
