Disaster strikes, I find bud rot in a couple of the biggest colas of the centre plant, I remove the colas, salvage what I can, i now understand I have too little airflow for the number of plants in the tent, I am vigilant with looking for more bud rot, which I find in the biggest colas of the small stout indica plant, I presume its mostly indica from its shape, I remove, salvage and begin to dry what I can save
I install another more powerful fan on max speed with acoustic duct to keep fan on max speed, I install another fan to blow across the plants 5oo, humidity drops, everything looks good again to go forward, no further signs of bud rot
