I know they weren't looking the greatest. They were perfect until about 2 weeks ago. My water ph and tds was slightly high, and the nitrogen was a little high because of the emulsion, and I had a slight case of salt buildup that I removed and flushed durring transplanting. I have since invested in a 5 part reverse osmosis water filtration system. I've corrected the ph issue and cut back on the amount fed per week since the soil is already nutrient rich. they have since recovered, resumed regular growth and color. The picture was older and the yellowing was old growth. Here's some updated pics..
