Mine are grown in a mixture of MPC and about one third of grit. What they need is a well drained compost with a decent amount of food in it. I feed with half strength Tomorite about every two weeks until the flowering season is over, then with a half strength Maxicrop until the beginning of winter.
If yours are just newly potted up seedlings then they will not flower until next Spring. Babies are best fed gently with Maxicrop (or Baby Bio) for the first season.
Keep them moist but not over wet in winter and remove any dead or dying leaves as the season progresses.
This may be useful to you.
