Failed Grow

With initial highs of 80 and lows of 63, I finally was able to get a more consistent spread in temp and humidity with a portable AC. My ranges are now 77-65. At the tail end of the week I started seeing some discoloring, shown in photos. We're close to week 3 and so I started giving light nutrients to help with a possible deficiency. Growth seems to have stalled after a real fast start. Hopefully with tighter climate spreads and added nutrients the ladies will be more comfortable to grow.
