The past week has brought some colder weather to the Cali coast, and my remaining sativa have quickly taken on some fall colors. Green leaves yellowed over the course of three nights, took on some rust and purple tones at times. And the sugar leaves and bud tips are doing the same.
I’d like to give them another week or so, but wanted to ask the collective if there is any risk or down side to this coloring from the cold? Or is the cold merely going to slow down my growth but not do damage? (No frost to date, and none forecast for the upcoming week. Just low 40’s.)
