First grow

Progress seems slower than most grows I'm seeing on here, but they don't seem unhealthy. The first half inch of soil is dry, but moist passed that point. I water them every 2-3 days with 1/3 cup. I know I really need to get them out of the potting mix. Because the space will only allow 1 plant and I only have 1 bag of Coco Coir, I'm waiting to find out if which one is female. If they are all female, I'll select the which ever one looks the healthiest. I did upgrade my light from a 5000k Westgate LED parking lot light to a MAXSISUN 1000W LED Grow Light 3 days ago. I'm hoping that will help.
