I would stay away from Scott's and Miracle Grow everything--soil nutrients, additives. Did the soil say anything like "feeds for 3 months or anything like that? It is important to know exactly what soil you have them in.
First off, you need way more light right away. When we are talking about light for growing the equivalent wattage is not important, it is the actual wattage that matters, so you have 26 watts. Just to give you an idea, for 10 plants, you are probably ultimately going to need around 1000W of light....and not CFLs. If you were using CFLs you would need about 2000 watts.
I suggest that you do some basic reading so you know what you are going to need to take these plants to harvest. You are at the very beginning and this is a four month process, with lots of pitfalls along the way. Growing cannabis is not like growing tomatoes or flowers. Just to give you an idea, you are going to need a dedicated space that you can control the environment in--a closet or a tent made for growing work well. You are going to have to provide adequate light. This mean a minimum of 3000 lumens per sq ft of light in the blue spectrum for vegging and 5000 lumens per sq ft in the red spectrum for flowering. A 26W CFLs puts out about 1600 lumens. Because CFLs have such a low lumen to wattage rating, it makes them the most expensive, least efficient, and hottest of all the different kinds of lights that you can use to grow.
You will also need good ventilation. This means a good quality centrifuge type exhaust fan. The fan serves 2 purposes--it helps cool the space and it brings in fresh air that the plants need.
Next you need good soil and nutrients. I always recommend getting products formulated for cannabis. You can make up your own soil mixtures, but this is timer consuming. So many people buy soils already made up, like Fox Farm. You are also going to want nutrients formulated for cannabis. You will have to decide if you want to grow organic or non organic. If you decide to go organic, everything you use for your plants must be organic. With organics you do not need to pH your nute solution. If you use synthetic nutrients, you are going to have to pH your nutrient solution.
Growing is very satisfying and a wonderful hobby. But like most hobbies, it is going to take an investment of money to do it right. There is a reason that cannabis is expensive. It is expensive and can be difficult to grow. Every plant is going to require individual care and setting up a proper grow space that is going to yield something at the end of those 4 months is going to take money and knowledge.
Good luck on your journey!
