Could harvest now or wait a bit, your call.
The yellowing is almost like it wants more N but I feel this is natural fade as some parts a bit curled indacting burn from nutrients.
I would not have the fan that close to the plant, or point it at the wall to diffuse the wind. gentle breeze, to much and it can stress it.
