Northern Lights Autoflower

Performed a large defoliation this past week. This is slightly earlier than I would have liked too but I am struggling to reduce my humidity. I figure it could take the autos more time to recover from a strip like this as well. I have been trying to dehumidify the air outside my tent with minimal success. Need a larger intake fan. I am also curious as to why the two plants (left) that were not topped are so much smaller than the topped plants. I figured this would be the other way around but they are double the size. This brings up a lighting issue as my light is extremely close to the bigger plants but rather far from the small girls.
