My Plants are 12 weeks Flowering & Not even 1% of the Tricombs have turned red/brown

Aloha's, I m on my 2nd harvest in 2yrs. But I'm having issues with all 4 of my plants. & one of those are a "Girl Scout Cookies - Premium" originally a clone from HarborSide & is on its 12th week of Flowering yet not even 2% of its Tricombs have turned red/brown.
Actually all 4 of my plants Tricombs aren't turning colors like my last harvest. I have a 5ft Jack Herer, 1 5ft Girl Scout Cookies premium, & 2 6ft Bubba Kush plants, & all have been under my 600watt reddish/yellow grow light for 12 weeks now & normal flowering time is 9-10, but not the case with this batch for some weird reason. They look beautiful thick & pungent, & all the Tricombs on all 4 of my plants are creamy milky cloudy white & all super healthy.
Can anyone help me? What did I do wrong? Why at 12 weeks does none of 4 healthy plants still have no reddish/brownish Tricombs?
This is my medicine for a while, so I don't want to risk harvesting while there not fully ripened, there for nullifying all my hard work & aloha I pour into each plant. I just want to maximize potency & harvest right on time. So if anyone has any heads up or have gone through an extended flowering stage with any of the strands I just mentioned, then please by all mean get me LEARNED
Infinite Mahalo's to all those partaking in the healing of a Planet.

hows it brotha? im just a howly out here in norcal but i rep the 808 on my skin as i was married there and plan to retire there sum day. anyway do sum reading on here about amber actually signifying a degradation of thc rendering it worthless. seems to be a large debate right now but mr2shim has alot of info on it if u can find him. anyway i think u can harvest now is what im getting at.

Four good sized plants under a single 600watt? There is your problem. Being you have three different strains all with same issues it's not the strains, it's your environment.

Ooooo that's gr8 news my brahdah��
But ya, as u can imagine how an average savage such as myself with every thing on thee interweb saying red Tricombs at 60% is supposedly perfect. & at the dispensary I go to here in NorCal where I recently moved to from Kailua Town OAHU
Any ways as I was saying everything I've read & my dispensaries after inspection with my 100x microscope thingy & my 40xJewelers loupe can see on there herbals greener then the ninja turtles see they got at least 60% amber Tricombs. & that Dutch Treat was fudgen Amazing, best herb I ever had & still have left.
But I am very interested in New information especially when it could possibly benefit my situation right now seeing as I'm 2 weeks over recommended maximum flowering.

Just wish I knew for sure if that amber when degraded is actually CBD, in which if that is the case I like CBD..hmmmm so many important questions I need answers to this late in my flowering stage.

Infinite Mahalo's tho man, preciate the info

attached is the Size of my grow room, w/2 industrial oscillating fans, HEPA filter, & I rotate my plants every day 6hrs in on its normal flowering of 12/12

its actually cbn not cbd. the cbd is a different compound found to actually target pain receptors and other nerves without the psycho active effects thc has. generally high thc means low cbd but in recent years ive perceived a change and see more 15%thc and 3-5% cbd as opposed to 8-10%thc and still only 3-5% cbd. hit me on a pm if u anywhere between sac ans san jose as i deliver our products to many dispensaries between those towns.

i'd chop those bad boys.. 80% amber is way too far imo, as has been said, amber means the trics are starting to degrade and past their peak..

i usually never tell people i think their plants are ready, but i think your plants are ready..

No there is Zero amber Tricombs on all of my 4 plants. & it's now on its 12th week of Flowering
Now knowing that there isn't any amber Tricombs, do u still think I should chop'm down?
they look amazing, super pungent, all creamy cloudy white Tricombs permeate each bud even half way up each leaf. But I was under the notion that 60% amber Tricombs was ideal, is that not the case any more ?

If those are your plants they look ok, not amazing. Theyre nice but i think they look like they can still put on some weight. Its probably winter so you might have a longer or less than perfect crop. It happens. Watch the tri's and go with your gut

I agree with poster that your lack of adequate light has prevented timely conversion from cloudy to amber trichs. If you want to play it safe, harvest one now and check it out over the course of a week's time to give it SOME drying benefit (as opposed to nuking it, which is harsh). By that time, you'll see if you've made any further progress toward amber. Also, remember that the tendency toward sativa tendencies (cerebral high) are greatest at early harvest and the indica tendencies (couch lock) tend to get enhanced later in the harvest, i.e., when you have more trichomes. Some of it comes down to personal preference, the rest to genetics and environment. You can aid the later by adding some lumens, preferably hps, to the final days of your grow. BTW, 60% amber is a myth. You will have lost much of your potency if you leave it that long. Most texts say between 1-20% amber is your target harvest. I happen to choose 10% because it works for me.

Thank u man, very much appreciated for ur direct help in exact percentages, thank u

I've heard of some strains that do not show trichome coloring despite being done. Am I wrong??

In my opinion you don't need to let them turn amber cloudy is when they are at there peak when they go amber they are degrading I try to chop at al cloudy
