First indoor grow

First week of bloom was uneventful until feeding. After feeding upper leaves began to droop and looked more yellow. Seems like growth has slowed since feeding. Edit: Looking back at photos now. Growth has continued since last feeding but had seemed slow. Before this feeding I felt like I was starting to get a handle on watering. The leaves would start to droop just a small amount and I would then water. Soil would be dry only at the top. The plants would then perk up by the next day. This week after the first bloom feed the plants did not perk up but instead drooped way more than usual. I am not sure why this happened. I have also seen some signs of nitrogen deficiency with yellow leaves at bottoms of Aurora Indica plants. At the moment I am wondering not only what my problem is but also if I am just over-reacting and in fact don't have any problems.
