I bought this meyer lemon a eeek ago and repot it in relative big pot with citrus soil without removing old soil. Im watering once a week and it is bit warm inside. I don't know if moisture level is good enough in pot or not. There was only one leaf before but now there are two leaves with burning tip. Im not using any fertilizer yet because i repot it a week ago. If i need to fertilize it then what do u recommend? 3-2-5 or 7-2-5 are available here and im in Sweden south.
