Hey there CaliGrown, they look super frosty, beautiful!
Can I suggest that you refer back to the photos of week 11 flower, the fan leaves towards the bottom of the plant begins to lighten up, limey green/yellow..?
I would consider that you continue 'grow' nutrients just another week longer next time round? Seems there was a slight nitrogen deficiency due to the fact they used loads of N up,during that crucial stretch period.. I believe you may of cut out its N supply just a week early?
From my experiences, I've found I get better results if I delay the transition to flower nutrients, usually until the start of 3rd week flower, as the stretch begins to slow and come to and end. Helps to keep those leaves greener and prevent early bloom autumnal fading.
This is just my advice, by no means gospel, but if you did wonder why the leaves changed colour at this stage, it's some food for thought. All the best finishing up, I took my G Zkittlez to Day 67 of 12/12 if that's any help, your in for an absolute treat π
