I use my fans no higher the med if they are hitting planties, and add another fan if you need, and a timer for your off cycle,so the plant gets a rest from the wind stress. Alternate the fans in the dark cycle{timer} so you still have circulation, but plants are getting a rest from keeping up with the wind{chapped lips/leaves} My observation is a plant{varietals vary} that is tighter in its pot will be more apt to be stressed by the difference in intake air{temp/humidity} before it warms in your room, especially if a fan is blowing the cooler dryer air direct on planty. hope you suss it out peace
Marquis de Sod are you running an ozone generator?
I looked at your pics again and thought I'd quote myself from this thread. Usually smaller plants are the first to be affected.The pic you posted looks like what happens when you have high concentrations of ozone in the air. If you are running an ozone generator then I would bet that is the problem.
