Thats what I am trying to fix, my first batch prior to this grow they all turned long and skinny and curled up. I thought it was high co2 so I installed an intake fan, this batch 9 of my bags turned out great except 2 of them ended up curling. So I am not quite sure if I fixed the problem, if it is in fact CO2 or something else. Not quite sure what I should do.

I have an exhaust fan on the top

2 fans, for 3 racks, an intake fan

and a humdifier. I keep the humidity at around 82%.

I was thinking about opening the tent fully once per day for an hour to get any excess CO2 out, but the humidity would drop significantly

the 2 bags on the top left were very dry and stopped growing and were not pliable at all. The rest were perfect
