First Auto Run - AvT

I've been super worried about their size, I feel like they are growing really slow for autos and should be bigger, so I started taking daily pictures of one of the 2 AvT to monitor growth. Maybe I'm just being over critical and worried since this is my first auto grow and I know the first few weeks of growth are critical for an auto I switched to 18/6 schedule, I wish my temps were a little higher at night (63-65) but there's not much I can do about that. My daytime temps have been 77-80 which I like, i just hope the temp drop at night and humidity rise doesn't effect them too much. Any advice or comments are welcome. Happy growing!
