Looks like this soil is peatmoss based with wood chips and perlite, your soil is probabbly acidic (5, -6 pH) (I have no idea whats the ideal soil pH for BC is)
small pot - dont transplant at the moment you will stress it to the point of death or stunnted growth but in the future when its established and healthy looking transplant it)
give it filtered direct light its small and gentle and probabbly lacks soil/air moisture.
Before you planted it, did you soaked the soil with water? If not then there are probabbly pockets of air within the soil where roots wont grow very much, that in the combination with small clay pot, avoid clay pots, do you apply any fertilizer? solutions or solids (organics)? Is the soil nutrient rich or not? (check soil bag label and share what it contains if it contain anything) tell soil pH too.
What you can do now: Give it filtered direct light with air movement (not too much, a breeze), good waterings with some N-P-K fertilizer more on the N-P, with about table spoon of magnesium sulfate (epsom salts) dissolved in a 1L water (dont use the whole liter to water it, just enough) consider a foilar feeding solution AFTER the direct hot sunlight (else you can burn the leaves).
