Hi there AllTheGreen, first, i'm impressed with your first grow, i'm sure if you join the Newbie contest you will be very competitive ! Second for light mix, i would not recommend it, light mix is peat moss which is first of all unsustainable the way it's mined. Second it's a sterile medium so you have to add your own beneficial bacteria to your medium, it just doesnt make much sense. Third it retains quite a lot of water for quite a long time. That seems like a good thing, but it's really not, it will lead to water stress, some extra difficulty with water mold in the root zone etc. Plus cannabis plants really like wet dry cycles, the quicker the better, that's why coco works so well, and so much better. One thing i do that you can do is to get light mix and soil , then layer your pot. So you start with something on the bottom to do drainage, then mix your light mix with perlite (30%) and your soil with perlite (also 30%) separately , then do one layer light mix, one layer soil, one layer lightmix, one layer soil, seven times or so. That way you have the benefits of light mix and perlite and soil at the same time. The end product just tastes better. For the rest, like biobizz nutrients, they're not my favorite but they're also not the worst, it should be fine to work with it , i'm sure you will do fine. Just one recomendation , when you make your nutrient plant, choose one NPK , always use calmag, and use an additive also, like humic acid, beneficial bacteria, or enzymes. Hope this helps ! 🚀
