With autos honestly you can really mess about with the timing and see what works for you. One of the beautiful things is being able to increase the light schedule during flowering! I do 18/6 in the first stages of life, 20/4 in the veg/bloom phase and then 23/1 in full bloom.
A little weird i know but there really isn’t any reason why you can’t, the regions ruderalis grows in will often have very short and sporadic summers so while rest is beneficial, once a strong root system is developed there isn’t as much benefit in dark time.
Tilda seemed to respond very positively with lots of trich production shortly after bumping up to 23/1 though i can’t be sure it directly linked though it’s a vast difference from the 18/6 on Val at this age
All my trichs on Greta are also completely cloudy with very minor ambering coming in though ive actually seem that a lot of autos simply do not amber the way a photoperiodic strain will no matter what.
There’s a thread on here about once you have a healthy feeding routine and know what’s going on the best way to tell when to harvest is about watching old fan leaves to tell you apparently because of the fact that amber isn’t assured.

Pretty interesting and think i’m going to use that method alongside the standard microscope checks, just thought i’d share since someone reminded me of it and you’re getting to time where you need to start thinking about it
