Never trust a doctor who's plants have died.
Looking hella frosty.
Not surprised you only got one A/C unit bud. Your techniques appears to me to be highly adaptive to changing (unexpected) conditions. Your always have exceptionally even spacing of budding along the length of the plant, (never too thick or thin) and I notice you never deviate from that hardly. Your plants no matter the strain appear to be remarkably consistent in overall size/shape, and look remarkably well ventilated.
The short squat plants that I've been growing can easily develop problems if not watched really closely, and humidity kept in check. The huge downside to being area confined. I've tried to mitigate it some by increasing ventilation, but that only helps so much.
Like this one, it's so short and squat, I think I need to thin her out again....
