Use a trusted soil/compost company and feed light, you only need full strength nutes if you've got big old plants. Also since your starting u again why don't you try Coco Coir. You'll never look back.
Looking very good Lynk, how about a little training for those girls, why don't you super-crop the main leaders and raise the pots a few inches? , this will then give more of an even spread of light to both of your girls.
Variety is a natural occurring cross of the same species, cultivar has had human intervention to create it. When describing things in the plant world it goes like this
Genus. >. species > Variety. Or Cultivar
G81. Hope that helps
P.s. Sometimes you get crosses between different species...
Happy Christmas one and all!
