Ok, Denise, I see what you have. What I'm going to do later is calculate ratios for each of the three soils in the three soil system based on the pot sizes you want to use so you don't end up with way too much of one soil and not enough of the other.
I already suggested pot sizes in PM, I think, but I'm curious about your current preference for flowering. Are the fabric pots you are flowering in now 5 gallons? We should establish standard pot sizes for each stage of the grow, younguns, adolescent teens, and sexually mature flowering adults. We can work with what you have on-hand. The sizes of pots will change how much of each soil you want to mix.
Fabric pots are great for flowering. You won't want to use them for veg because you are going to have to transplant a fairly large plant into a bigger pot right before switching to a flowering schedule. In my experience, removing a decent sized plant from a fabric pot is a challenge, while standard nursery pots are a piece of cake.
Once you get the soils mixed you will need to wait a couple of weeks to let the soils stew before any plants go in them. Remember you want soil storage bins in the 25-30 gallon range for the veg and flower soils, and something around 10 gallons for the baby soil. Once the bins are on hand and we know the pot sizes I'll scale the recipe for your needs in easy to measure units.
