Im getting some of the same curling and color variagation on a cbd lemon-aid plant that Ive been growing for 3 years or so and Ive never noticed it before. Could my nute regimine be causing it or could mites be so elusive that my daily scopings are missing them?
my plants had very similar symptoms that was from heat stress, not enough ventilation. it got really hot for a couple days and the damage happened very quickly i thought it was bugs at first.
