Rum Runner

I did final transport into 2 gl fabric pots with happy frog soil. I've increased the watering to 2 cups every 48-72 hours with a nice spray to get the leaves and the top soil. I also bought this grey container that you add water to and it feeds your plants CO2 for 2 weeks. There are some plants that are 9 in but majority is about 6 3/4-7 1/4 in tall. They seem like they will be bushy. And lastly some of the leaves on 2 or 3 plants are curling inward so I'm curious to understand what's going on. I haven't gotten nutrients cause the soil has enough for 30 days and by that time it will be 4 weeks left in grow and switching to flower so I may use some the 1st 2-3 weeks after veg and flush the last 1-2 weeks.
