I'm not so sure. I think never going amber would be weird as its just part of every organic thing ever. It turns to brown. See it every day.
But my Farmer buddy told me recently about of the 27 podcasts he listens to each week that some of the highest testing THC strains around at the moment have different shaped trichs.
I'll have a look back through our 1000's of messages we managed to get through for the podcast.
So shape change:
Classic trich right? Ignore the fact its super clear but it has a ball on top, right?
I can't find a picture to properly illustrate it but apparently the highest THC testing strains don't have a ball, a globe, a bulge at the top.
But they have much higher density which gives them the upwards overall tick on THC.
I haven't listen to it but we speculated that without the globe casting shade they can grow closer together, a sort of bred for attribute. I mean - it was probably just a mutation, doubt anyone set out to do it, but some people may have spotted it and bred for it.
Anyway I'll hunt out the podcast.
I think btw - me The Farmer and The Terp KIng are close on getting a podcast (not for profit/money at all) together. If Rob is OK with it, and its OK to listen to I'll put it on Vimeo.
The Terp King about to start his first real grow in Spain in Rockwool. Me and Farmer got popcorn to hand. Gonna be funny. A better smoker than grower is TTK!
