Hey wild the buds are looking great, you should be very proud. The trichrome photos look good and healthy you seem to only have a short time left. In regards to the cold temps and colors, some colorful strains will never change even if you freeze their tits off, my outdoor got down to like the 40s and still only had minimal color, i think its just luck of that seeds phenotype but the next may be purple who knows? Again luck of the pheno. If you're going to do some temp adjustments just I advise you to monitor everything very closely as when most plants get in the range of 60 degrees thats where PM and other boogie bears thrive. I hope you get the colors you're looking for, but at the very least you'll get the beautiful green/orange associated with very nicely grown plants. Happy holidays ✌️
